Duo Mobile

Duo Mobile [Business] App Description & Overview

Duo Mobile works with Duo Security's two-factor authentication service to make logins more secure. The application generates passcodes for login and can receive push notifications for easy, one-tap authentication on your iPhone, iPad, or Apple Watch.

Additionally, you can use Duo Mobile to manage two-factor authentication for other application and web services that make use of passcodes.

Duo Mobile Comments & Reviews

TransferWise 💸

Enjoy high maximum transfers into more than 20 currencies while saving up to 90% over local banks! The cheap, fast way to send money abroad. Free transfer up to 500 USD!

- Was fine until I needed to transfer phones...

My school forced me to use Duo for 2FA. After one of my personal social media accounts was hacked, it prompted me to look into 2FA for them as well. I wish I would’ve looked at the reviews before adding my personal accounts to this app. Everything was fine until I got a new phone and needed to transfer my Duo to this device. The process has been an absolute nightmare, and the only “help” I receive is a long wall of text which vaguely describes what I need to do but no instruction on how to do it. My instant restore option is switched on for both phones, but I get no option to restore old codes like the help center claims I should. I’m at a complete loss for what to do and it seems that the Duo website and help center doesn’t exactly know either.

- Employees need some control

*** Please read MORAL implications I am not writing to critique the app itself as I just downloaded the app. A small background, I work for a company who now require this specific app to be downloaded on our personal phones, or we will have "resigned" from the company. My immediate problem with the app is it gives all control to the company, including the control to direct the app to change my phone, and no ability to turn off the app while not at work. I feel if the app is being forced on employees by employers to save them money, it should be a "moral" obligation on the part of the developer to give the employee (owner of the phone) some control over the app and how it may function on the phone. But instead, that area is turn off to the employee and total control is granted to the employer. In my case there is no on/off toggle where the app could be shut down while not needed to perform work functions, and thus reducing the employer's ability to mis-use the app on your phone on your personal time. Please consider the MORAL obligation to allow the person who is being forced to use your app to have some control how it will be used on their own personal phones. Not everyone works for company that are completely trustworthy. Just because the company made the agreement with you, should not automatically eliminate all rights employee may have over their own personal property, nor give 100% control to the employer over a non-company own phone.

- Handles an annoying task with aplomb

I hate the time required to perform two-factor authentication, and so was dreading when my institution began to require it. I was pleasantly surprised that the Duo app handles this task rapidly, much more so than any other app-based or text-based method I’ve used. Usually within about 2 seconds, I can approve a request with a single tap of my Apple Watch (the notification includes an “approve” button) or via two taps of my phone. I wouldn’t hesitate to switch to this system for any other account I use. EDIT: looking in another review, it appears that I could also be quickly approving with a single swipe or 3D-touch and tap from my phone. Perhaps a brief blurb instructing this within the app would be helpful because I would have been doing so all along!

- Misplaced blame

After reading the negative reviews, I’ve come to the conclusion that people seriously need to take a moment to understand HOW 2FA works, WHERE and WHAT the roles/responsibilities lie and are for each vendor (eg Coinbase vs Duo), and WHY 2FA is important. Is the app perfect? No. Does it work well for what it was designed to do? Yes. Can it be improved? Yes. Here is my wishlist to improve the usability of the app, hopefully the devs are reading! (1) I have well over 50 tokens (many from the same service), please introduce folders or a way to organize/group tokens. (2) Allow for custom icons instead of restricting it to just the ones you’ve decided to include; this would also help me find tokens more quickly. (3) Allow for token access from a widget on the lock screen (either display passcode or tap to immediately open the token in the app).

- Interface, interface

As far as working as a 2fac this app is fine, it does that. The issue with it is that it’s a really simple app but has an annoying interface. If the buttons for the push notification could be moved to a more thumb friendly location that would be great. It’s just a screen with 2 buttons, there’s no reason to make me adjust my grip on the phone so I can reach the accept button. I should be able to pick the phone up and hit the button in one motion. Not pick the phone up fumble with the position in my hand then hit the button. It’s annoying and unnecessary. The whole screen is there to use for this purpose and is empty. The buttons are large but the phone screen is also large and it puts the buttons out of comfortable reach for one hand use. Stack them in the middle or something. Maybe a flick gesture, or both, I dunno.

- A great option for 2FA

Seeing all the low ratings based on a business’ or university’s decision to apply additional security to their networks, I had to add my two cents. It is 2FA, not Duo, about which most are railing. If you don’t like 2FA, rid the world of hackers and thieves that will use every available means to get into any network they can. Until you accomplish that, accept the fact that for those trying to secure a network, 2FA is a necessary precaution, much like a deadbolt on a door. And Duo is a good method for applying 2FA. We primarily use Duo Push for accessing our systems and it works very well. Unrelated note: Duo works much better than this rating system, which will tell you after the fact that a nickname has been used but won’t suggest one that hasn’t been...

- Almost perfect!

I love the interface and how there is a variation of event based logins and OTP requests depending on what security factors are necessary for what apps and services. My wishlist of features mostly consists of needing a complication on my Apple Watch to easily access to the application, rather than needing to search or find in my App Library on the watch, as well as widget access on the iPhone and iPad for further quick access to each OTP passcode I need to type in, as they don't always send push notifications when there is a login attempt made. Other than that, I think the app has come a long way and is user friendly with security as its top priority which is what I would want for any service like this

- Love it - but Apple Watch app seems to have a bug

Edit - issue seems to have been fixed. Also, leaving the Duo app running in the background on the phone, which I hadn’t been doing before, helps. I implemented the free tier of Duo to safeguard my personal VPN against unauthorized access. It works great and having an Apple Watch app is neat too. But recently, I noticed that my watch app wouldn’t generate passcodes anymore. Push notifications to the Watch still work. Restarting the watch seems to work once and then it won’t give codes anymore. I couldn’t find a way to send feedback in the app itself, so I decided to leave a review. Hope this minor bug can be ironed out so I can get back to enjoying that extra convenience!

- New standard

2FA seems to be the new standard as far as consumer security is concerned. At first I was a bit frustrated with the inconvenience of having to use my password and phone to log on to my university account, but the added security is definitely worth it. There so many malicious actors when it comes to attacking university data and this switch to Duo Mobile is for the better. Couple of tips: remember to keep one time passcodes on hand, and allow third party accounts to reconnect automatically (for when you reset your phone or get a new iPhone). Definitely recommend this app not just for school accounts, but any other account you want to add extra security to.

- Stop deleting my reviews, cowards

Truly cannot imagine a worse method of 2FA. Why can’t I use Face ID? Touch ID? Or just a push to my laptop? But no, that would make too much sense. Definitely better to require the use of another device, because logging in to canvas needs to be more complicated than logging in to my BANK. This app is terrible in every sense of the word. If you are an administrator or employer requiring others to use this, you should be fired. On the spot. Using this app is overly complicated and frustrating, not to mention a poor decision—if your phone is dead, you can’t log in. If Duo had a desktop app I wouldn’t have complaints, but the use of a whole other device to log in to check my grades??? Overly and unnecessarily complicated. If you are considering the use of this app as 2FA, I am BEGGING you to consider any other option. This app is terrible and deserves to be taken off the App Store.

- Very Difficult

At first the app was going well for me, but then i got a new phone and the app didn’t transfer over so i had to redownload Duo but the thing was, the app wasn’t connected to my apps (Snapchat and Instagram) anymore but my apps still required the codes. So i tried going on Duo and clicking “Looking to recover your accounts?” at the bottom of the screen and it was frozen, as in you weren’t able to click it but everything else worked. So i looked up a solution on safari and nothing came up that would solve my problem except for Androids and i have an iPhone. So i’m currently permanently logged out of Instagram.

- Nice and easy

Pretty straightforward and works to a T. Anyone who wrote a 1 star review are just people who create problems for themselves. Get this, one guy says it was duos problem because his child and him weren’t able to effectively communicate when to use the 2 factor authentication. Another guy, said it was such an inconvenience that the accept and decline buttons were placed at the bottom of the screen. Like it’s 2 factor authentication, why does it matter that the button position isn't in the optimal space? It literally takes 2 seconds to do this but apparently it’s such a hassle. Nice and easy process

- Reliable two factor authentication

We've used DUO for several years for two factor authentication. It's secure and reliable. It definitely gets the job done. The app isn't too bad, but could use a little more polish. Namely, I wish the buttons fir approving or disproving a log on attempt were positioned a little higher and made a touch smaller in the app to make one hand use easier. The buttons are large, going to the screens edge. I have accidentally hit the button before when picking up my phone where the palm of my hand touched the edge of the screen in just such a way that it registered as a click granting approval. Luckily, it was me trying to log in.

- One of the most convenient 2 factor authentication apps

We were told to use this app for 2 factor authentication by my university. I checked the reviews and saw a lot of very poor reviews and kind of went “oh no.” These reviews as far as I can tell now are mostly just people who were also required to use the app, and had never used two factor authentication before. The app has been bug free for me and has the most convenient approach I have seen. They are complaining about two factor authentication as a system and being required to use it, not how well the app functions.

- Duo mobile with instagram accounts

So I decided In November 2019 to secure my instagram account using this app. Everything was working fine until I had to reset my phone I made sure my login was saved on my iCloud so I wouldn’t have no problem with signing back in on this app. Turns out duo mobile never saved my information on my phone or on my instagram account. I tried to email about this problem and all I got was there’s no account associated with the email I used for my instagram account. I cannot login to my instagram anymore because I used this app as a 2 factor authentication for my instagram and I cannot login in on duo mobile or my instagram account anymore I’m very disappointed that I put my trust into this app and nothing is helping me get my account logged back in.

- Great Authenticator App! Don’t mind the harsh reviews.

To be truly honest, this app is a wonderful authenticator. The interface is incredibly user-friendly and allows you to clearly identify the account you want to use (through the website’s picture/ logo). If you have used other authenticator apps in the past, setting up a manual account is the exact same process. Having a host set up MFA, such as a college, is an even easier setup. I use this for most of my online accounts and Duo Mobile has been quick, easy and efficient. I flat out love it. Keep up the great work Duo!

- I would pay to not have to use this

Daughter’s university recently implemented usage of Duo. If I need to log in to pay something, I have to wait for her to get the approval. The problem is, we are in different time zones. So she may be asleep when I need to access her account. It is extremely frustrating, and there should be a way to have two different devices authorized for approval. At times when we are together, there can be a lag when she gets the actual notification. As others have mentioned, if you don’t see the notification pop up you can easily miss it as it doesn’t stay on the screen. Please make an option for two devices...it would also be helpful for when you get a new phone and still have access to authentication on the second device.

- I can’t get into my college classes

My university recently mandated duo (ugh) and it works terrible. I had an old phone short circuit so the screen is black and the iCloud backup failed. I tried to download the duo app on my new phone and it keeps prompting me to go on my old phone (can’t) or use iCloud (can’t). So apparently they are just going to lock me out of my own college account. Truly a bad company. Why would they assume that people can access there own devices and iCloud always? Truly I pay thousands of dollars a year to not even be able to get into my own college account. They need to fix this. Duo has always been a pointless hassle at best (what if I forget my phone or it’s dead? I just can’t log into my computer?) now it’s actually unusable and locking me out of important info.

- No more ex gf drama

Since everyone is complaining about 2FA itself rather than the app functionality, I’ll add my note on why I’m glad my school integrated 2FA... My ex-girlfriend constantly logs into any account she can get access to. She uses different devices to sneak her way and she guesses or knows most of my passwords. I’ve had to change passwords (and then immediately forget them) because she’s always logging into my accounts without my knowledge. Finally some peace of mind knowing she can’t do anything weird with my most important account. Thanks, Duo!

- Simple and intuitive

So many reviews panning these guys for stuff that isn’t their fault... The Duo app is the best 2FA app I’ve used. Adding new accounts is a breeze, and the hold-to-copy function makes entering passcodes a piece of cake. Additionally, certain accounts can use push notifications for authentication. I use Duo to secure several accounts and it works exactly as it should. I guess I’d have to say don’t set up 2FA if you don’t know what it is. All the bad reviews I’ve seen are from people who don’t understand 2FA and really shouldn’t be reflecting on this app.

- Could be better

I recently started having to use this for school and it’s a major inconvenience, but that isn’t all the developers’ fault. I really think they should add some kind of “trusted device” feature that would allow users to have one computer that you wouldn’t have to go through two-factor authentication every single time, but maybe just the first of every month. It’s annoying not being able to check my grades quickly or look at an assignment quickly on my own computer. I hate that I have to use this but the developers could make the experience less painful

- It’s not the app

This app works great, it has worked flawlessly since I started using it a couple of months ago. All the one star reviews are about issues with using 2 factor authentication, not with this app. If you don’t back up your phone to iCloud, that’s not this app’s fault. If you delete this app thinking magically 2FA is going to be disabled, that’s not this app’s fault. If you are not the owner of the account and want to get into the account on the owner’s behalf and have not requested a second device, that’s not this app’s fault.

- Simple and Effective

It seems most negative reviews are blaming the wrong players. Duo facilitates the 2Fa but is not the company that is mandating it nor are they the ones controlling which features and elements you have access to. If you’ve used literally *any* other 2Fa platform you will see Duo is by far the best in the market. Simple and effective. Time necessary to log in is reduced with their quick push to phone and simple single button approval. The watch app works flawlessly. I have not had a single issue with Duo.

- Works Fine, but needs a desktop version

This app works fine for my university 2FA with a combination of a pin and push notification however, plenty of times my phone has been out of battery or the class strictly does not allow phones and I am not able to access my assignments, quizzes, tests etc. If there was a desktop version of the app that would be amazing. I do not see a huge security risk for this either, because if someone already has gained access to your personal computer, you may have many other unsecured important things to worry about such as auto fill passwords and logins.

- Review that actually covers the APP...

Got a decent laugh reading these 1-star reviews. The following apply to almost all of them: -Mad at Duo because they didn’t retain recovery key for Instagram -Mad at Duo because the company using their service failed to educate their own people properly -Mad at Duo for “making” them use 2FA Sad my actual review and 5 star won’t make a dent in those 1 star ratings. Here’s the truth for actual paying customers who may read reviews. This app does what it’s built to do, with a high accuracy rate. Any user having issues with the app I’ve seen so far falls under two categories; not reading setup instructions or false expectations of how it should work. App pushes fast. Offline login methods work. Tech support is very responsive. Customer success is their focus. I don’t work for Duo, just felt a well developed app deserves a fair shake for any non-teen that may be reading.

- Don’t believe the naysayers

If you read the negative reviews, you’ll see people are complaining about two-factor authentication (2FA) in general. Yeah, it is an inconvenience. The advantage is increased security. Most of these people should be complaining with their IT departments or any service that requires it. Unfortunately, Duo is what they see when inconvenienced and this blame Duo. If you ever had to use a different 2FA provider, then you would realize that Duo Security is leagues better than anything else out there.

- Terrible communication

I happily used Duo Mobile for years before I switched to a new phone without thinking to update my accounts. Had I known that at some point I could have started backing up my authenticator codes to iCloud, I would have done so. Now, I’m locked out of two of my most important accounts with no recourse. This could have been prevented with a simple pop up, text, or email to users notifying them about this feature. Even if your job requires you to use this software for your corporate login, stay far away for personal use. While your IT administrator can help you authenticate in, they shouldn’t have to do the extra legwork because of Duo Mobile’s failure to communicate with their users.

- Complete garbage

I been trying to login into my school’s website and I’m unable to. FOR SOME REASON, EVERY TIME I PUT THE PASSCODE CORRECTLY, it says incorrect passcode even though I have it correctly. Then I go on Zoom which by the way has been better help since it’s telling me my account is locked due to excessive authentication failures. WHAT FAILURES?!?! I have always been able to login into my school’s account without any problem. And I know I been typing and always type the correct passcode to prevent that. I WANT HONEST HELP, not some website telling me what to do if I need help. Not some website that is not exactly describing this problem. I have to login with my credentials to my school’s website for Zoom on Monday. This is a complete mess

- Locked out of account

This has happened to me so many times and it is so annoying. You reset your phone, your phone dies, you don’t have WiFi, and you can’t login to your email or into the school website without this terrible feature. I would pay more money to not have to use this. If you want to get back in or into any duo settings to fix the issue, you would also need a 2F verification. Great intentions of the app and nothing against the developer, it’s just a terrible inconvenience to someone who is forced to use it and can’t get valuable access in time sensitive matters because there is no way to get in your accounts without calling someone to reset it for you.

- Good app but can’t get codes

I got this app to help protect my instagram account from anyone who tried to get into it. However, my account was accidentally removed from the DUO app and now cannot get codes to login to the Instagram account. I’m now stuck, unable to get into my Instagram. I’ve tried by best to get it back, a whole week now, but nothing has worked. It seems it works too well with security or that there is no way back in when you don’t have phone number or gmail connected to it as well. Since I can’t log back into DUO, I also can’t get codes for Instagram. There is also no human help.

- Garbage app that bricks you out of your account

There’s no point in reading this review! You are going to be forced to download this app because your school or work thought it’d be secure or whatever and there isn’t an alternative. Then when your battery dies or there’s an update you’re freakin bricked out of your account I can’t access my college account because of this app, and I need to order books, switch classes, and get a parking spot. The app won’t even open it crashes immediately and I’ve restarted and made sure it’s up to date If you’re an IT person looking to make your login secure, I beg you to not use this joke of an app and use literally anything else

- Push notifications no longer working (updated)

UPDATE: Thank you to the developer for responding to my review. They recommended I ensure my iOS is updated. It is, and that doesn’t fix the problem. I also went to their recommended help pages. They also did not fix the problem. I don’t know what’s wrong with the Duo system, but my login attempts just don’t trigger push notifications on my phone anymore. ORIGINAL POST: Before, every time I needed to login to something on my phone, I’d get an easy push notification. Now those notifications no longer show up and I have to go through the more annoying process of texting codes or opening the app. Please fix this.

- Needs Apple Watch Complication to quickly launch

I have to use this for work and overall use it almost exclusively on my Apple Watch - would love addition for support of a complication I can add to my watch face so can quickly launch as otherwise I have to hit the side button to load apps that I have added as favorites to the Dock and select Duo and adds a few more seconds which adds up over the course of the day as I launch the app about 20-30 times a day. Otherwise works great.

- DUO is the best 2FA app

I may not love having to do 2FA so much, but DUO is a great company and made a great inventive product that I’ve never had any problems with. I especially love push notifications where I don’t even have to open my phone I can just click and approve the login. I originally used it just for my required school accounts but now use it to back up as many of my accounts that allow 3rd party-app 2FA as possible. I will keep using it

- Very reliable

I’ve had Duo Mobile for years now and I’ve rarely ever had an issue with it. It stays up to date and lets you know if something is wrong whether it be the app is out of date or your IOS needs to be updated. It doesn’t glitch and the different options (such as Push, Call, or Passcode) makes it very easy and accessible to use. The one thing I will say about it is that it is hard to fix when you change your phone number.

- UI needs work on Apple Watch

This would get at least four stars if the UI on the Apple Watch matched the one on the iPhone. The iPhone UI selections cover two different corners and is easy to navigate. I love that Duo has an Apple Watch connection. The Watch face is much smaller than the iPhone, so why did they design the Watch so it’s much harder to use? The ‘Approve’/‘Deny’ buttons are thin stripes across the Watch face. I can’t tell you how many times I’ve hit the ‘Approve’ button and my fat finger has instead hit the ‘Deny’ button instead. It’s very frustrating.

- Overly complicated, unnecessary and annoying

My university requires duo for us to get in to our school accounts. That is a AWFUL decision. There have been too many times where I’m at school where my phone is dead or I simply do not have any reception and I’m unable to access my own accounts! Then that day I can’t get any school work done and get points docked for assignments being late 🤬 not to mention after a year of me not using the app while at a different school, when I returned it said that I need to reconnect but didn’t give instructions on how to do that, so the only way to log in is through calling me, not even text or codes work for me anymore.

- Why is the administrator in charge of how many devices i have??

Apparently the only reason the "Add device" option isnt coming up for me is because my 'administrator' didn't allow for that. Okay,, why even make that an admin option in the first place? My only device with my Duo on it is an old tablet that barely works. I have a better one now,, but i can't verify my university logins with it because the 'Add Device' button was blocked i guess? What is the point of that? After having so many different security measures, how is blocking another device from adding the account so safe? Please remove this option for whoever set this up, it is really bad.

- Relatively easy but

As a multi factor authentication app, this works reasonably well. Others have commented about button placement, which are legitimate. I would echo that the process takes more than one step to get to those buttons, which is unnecessary. Another issue is that the app does not update automatically. It simply gives a message that the app is “out of date“ and that I must go to the App Store to get the update. This app should update automatically, just like all the others. There’s simply no excuse for this nonsense.

- Useless app

My college uses duo for protection but it makes everything harder, and I’m not convinced that it makes our accounts any safer. Logging in is a hassle, communication between two devices is bad and sometimes does not work, switching devices is difficult, and the passcodes almost never work. I would pay to not use this app and go back to the way it was. I have experienced being locked out of my school information website because my phone was dead, been in class without access to my notes because I did not have my phone to allow access into my own account. This app makes everything harder.

- Works. Most of the time

It works and is pretty simple most of the time, my only complaint is that *sometimes* ( maybe 1 out of 10 times) the notification doesn’t show up in the lock screen so I have to open the app to accept it. Also if I have a notification waiting in the app it should always pop up as an alert as soon as I open the app to minimize the number of buttons I have to press. Otherwise it works as expected.

- Works fine but one issue

I use this app since my university has switched to this for user authentication. Everything works fine except if I have content and privacy restrictions enabled on my iPhone. If so, when it’s time for me to choose how I want to login, instead of seeing the push notification button, I just get an empty white screen. Please provide a fix for it to work with privacy restrictions enabled as I don’t currently see a way to tell it to.

- Needs improvement for watch OS

The iPhone app works very well, but the watch implementation needs work. There are 2 areas to improve: support for independent watch app for people who own the cellular version of the watch. When my phone battery dies I can use the watch app without the phone. Also if I forgot my phone at home I’m out of luck. Secondly the UI for watch should be improved, make the approve button on the top and dent button on the bottom not next to each other, fat fingered many times with the watch.

- App is great, can be implemented badly

I’ve been using this app for several years for work and it has always worked quickly and reliably. I can understand frustration if two factor authentication isn’t working since access to something important is blocked, but the problem is likely to be out of the hands of the people who wrote this app. Many of the one-star ratings seem misplaced.

- Absolutely Horrible

If there were academy awards available for poorly designed user experience for a mobile application, these people would win that award hands down and many times over. I teach UX (User Experience design) and this is a superb example of failure to even utilize effective label naming. Horrible UI and the documentation supplied is so amateurish as to better serve as pleasurable amusement. My students have done a better job than the —- who made this —-. Dear developers: please get in touch. I can set you up with a student who can at least write language on buttons as well as your instructions to make this comprehendable and thus usable by regular people.


The logic of this App should be improved significantly. My phone got reset, and I had to reset my account in DUO. In order to add my account back, I need to get a barcode scanned. In order to get a barcode, I need to access my account... In the end, I need to call the support guy to reset my account. There must be a better way to do so. Additionally, I literally don’t get why some organizations choose to implement such App when two-factor authentication method works so fine by sending people texts with verification codes, whereas for this one you need to first download an App and set everything up....... What a waste of time and energy.

- Duo is Comprehensive and free for personal use

I have been using Duo for several months now having transitioned from ping id, Authy, etc. Duo is an impressive platform. I love the watch App as well as the click to approve, looking at you Ping with your need to have me slide something 🙄. Duo also has great integrations with 1Password as well as a huge number of websites. This is a phenomenal way to upgrade your security stance because passwords are broken.

- Remember me doesn’t work.

This app was fine until the remember me button stopped working on my iPad. It’s frustrating to have to have my phone nearby every single time I want to log in to my school’s learning center (especially when I need to leave the internet back and forth to write a paper or something. I have cookies enabled, I’ve tried reinstalling and even deleting and re-setting up the account (and the internet apps). Nothing works. My MacBook’s “remember me” works and so does my phone’s. Both Safari and Chrome won’t let me select “remember me” on my iPad and it been driving me crazy for months.

- Two Duo accounts diminish functionality

This was working fine when I just Haden’s system needing two step verification. I could choose push, passcode, or call. Now that I have a second system added, the three options are still there. However, when I request a Push, I can only get a passcode. Then I have to cancel the request and change to passcode. This should be an easy fix, but there is no Help contact information.

- God awful!

More security is not what we need. A 15 character password followed by a phone call or push notification. They do not offer the option of texting the passcode to you so you are FORCED to download the application unless you’re available to take a phone call whenever you need it. This has got to be the most annoying thing that Texas State has implemented. It took an hour just to reset my email password and I am not technologically challenged, this whole process is technologically challenging! Figure out a way to make it more user friendly or Texas State needs to try something else ASAP.

- Upload other icons

Need the feature to upload our own icons for the authentication. The digits should also look bigger

- No search, can’t upload own icons,

No search !!! If you have dozens of accounts to manage like I do it’s hard to quickly find the one your looking for you. You’ll be scrolling forever. Can’t upload custom icons !!! The default list of icons is very limited, which would be fine if you could upload your own icons. But you can’t! This would make the app a lot easier to use as a visual icon is quicker to recognise than text. The good things are: +Codes are hidden until you tap on them +Dark mode supported +Attractive, minimalist design However, search for accounts is needed. Custom icons are needed. Better multi-device sync/support is needed. Duo Restore needs to be improved. Show us our codes are backed up so we can have peace of mind if our phone is broken/stolen we won’t be locked out of hundreds of accounts.

- No customer service

This company is really disgusting and I do not recommend going with them as your security authentication. They refused to help me gain access to my accounts and said I need to contact my third party companies which were uncontactable. Do not go with them.

- Poor user interface

App is unusable in real world scenarios. Only a small number of known applications are listed. When adding a 3rd Party app not listed it’s not possible to change the name, they all say THIRD-PARTY and it’s then impossible to know which one is which (my account ID is the same at each as well). Every other 2FA Authenticator our there lets you change the name of each entry. Why not this one?!

- works well

works well would like an ipad compatible version (landscape mode) latest update is a bit ugly, I've lost my icon as well, just the white wire frame icon. it's unclear on the website or in the app, but does duo mobile backup to iCloud? what happened if I delete it accidentally, or need to restore, are all my OTP service tokens restored or lost forever, requiring recovery keys for all the services in use?

- Too complicated

Signing up with the program is a hassle within itself, not to mention the complications with the poor interface design. But hey, at least it supports dark mode…

- Security Risk!!!!

Opening a notification from the lock screen enables a user access the iOS device without any requirement to enter a PIN or biometric effectively bypassing the security on the device and rendering the whole thing pointless.

- I give up! Your system is failing our business!

It is not working most of the time today and your online chat is failing too!!! Useless!!

- This app is a scam

I can’t get back into any of my accounts with it once the app is deleted you can’t get back into old accounts

- App won’t download

Using this app for work purpose and won’t download contacted duo support via live chat and said there’s nothing we can do?! Very disappointing

- ugh

the app logged my accounts out and now i cant get into my insta!!! :(

- Works with Apple Watch

This is an excellent App. I leave it open in the background on my iphone x and have duo in my dock on my apple watch s3 and generate codes without having to pickup my phone, which is great. I wouldn't use another 2FA app.

- Great so far still working it out

What can I use with it can I join my iTunes account? Facebook? Can’t think of anything else what just wondering what else u can the only think so far is Snapchat

- Brilliant app and a brilliant service

Brilliant app working alongside the Duo Security service. Brilliant use of the iWatch as well. This is the only app I found that was a must have for the watch.

- Very polished 2FA

Duo provides a very polished 2FA solution. The iOS app is simple and functional although the Watch push integration is currently broken with the latest release.

- i need help asap please

i can’t seem to figure out how to take the duo mobile of my instagram account so i’m just able to log in like normal without having to put in the duo mobile code. so i really need help please getting rid of it ❤️

- Excellent

Slick and works pretty much everywhere and with everything. 👍

- Brilliant simplicity

A great solution to the issue of adding multi factor authentication. Great with Apple watch too!

- Too easy

Love it because it’s so easy to love and works exactly like it says.

- stupid


- Very User Friendly

The one thing I appreciate with Duo is how easy it is for our end users to work with. The authentication pop us is convenient and reliable. Other MFA solutions often refuse to pop up, so the user needs to open the app and use a pass code instead. Or sometimes they notify, but then when you unlock the screen the notification has disappeared and again you have to find the app, refresh and hope the notification comes up. Once configured for your system user enrolment methods are also well thought out and easy for the users to follow. As it is a third party system Duo does not favour some systems over others. It appears to work just as well for all. It is a great solution for older systems which were never even designed for MFA such as older Remote Desktop Servers. Working in IT and I use a lot of different MFA solutions. Duo is still my favourite.


I hate this! I can’t get back into my Instagram account becuase of you since January I swapped my phone and I always used Facebook to log in and now I don’t know how to get the code off this app! Becuase idk what the key thing is?! I lost all my archived photos and memories becuase of this app! I DO NOT recommend 😐 if I could rate 0 stars I would. :(

- Urgent help

I can no longer log in into the Instagram account the code generated states wrong code despite it is similar.

- Not at all intuitive.

This is the least intuitive app that I have ever used, I suspect designed by a geek who has never spoken to a user in their life. The instructions are contradictory, (make a note of these three codes, you will need them to set up applications, then at the second code - never write these codes down!) I don’t know if it works well or not, I never got to the end of the instructions. Update. I was trying to use it with Bitwarden. Not at all intuitive and when you go to the instructions they are long, detailed and complex, I have worked in IT for 40 years so am comfortable with well written instructions, I do not find the app at all easy to use. It is difficult to trust an app that is overly complex.

- Can’t even Download it to my phone

I have an iPhone XR and I tried to download this app for academic purposes, but it won’t start downloading. Is there anyway this can be solved?

- So old school

Needing to download an app just to 2-Factor authenticate is so not user friendly. Had to use this for the University of Waterloo, much to my chagrin.

- Irrelevant

There are a lot of irrelevant comments with regards to why needing an app to do two factor authentication. This app does what it needs to do and it’s good at it. The rest is noise

- Works Great

A lot of the negative reviews are from whiny students who don’t understand the importance of security. There’s nothing wrong with the app, it works great.

- Can’t connect to new device

My sons phone was destroyed completely and had to be replaced. Now he can no longer connect to any of his accounts as duo is asking for an RC code we don’t have access to due to the phone being completely destroyed. Can’t find a reasonable means to contact customer support every article says ‘contact your administrator’ Who the hell is my administrator

- A real review

Alot of students here are whining cause they have to download an extra app, while i agree that’s slightly annoying, security is more important. the app is great and its really fast. I receive a notification within a second of me accessing my account in UW’s Learn.

- Not user friendly

Never know why there is need for such a useless and meaningless app!

- About the negative reviews

These random comments on here by people that have no idea what they're talking about is annoying to say the least. In the age of countless passwords and even more data breaches perhaps schools need to add identity security to their curriculum 🤷🏾‍♂️

- used by my company to spy on me

Forced to install by my company so they can spy on me

- An ill-conceived means to improve security

Perhaps some of the blame for the poor reviews of this product should be directed at IT departments and their implementation of this horrid 2FA system. Why does it force me to verify my identity in the middle of an IM conversation, for example? Idiotic.

- Doesn’t work as well any more

There used to be a pop up notification when I needed to approve/deny a log in but now there isn’t. I have to open the app, and tap to respond then tap to approve. Super annoying! I used to be able to approve in two taps without leaving the page I’m on and it doesn’t even tell me when I have to approve a log in! I was late for a meeting because of this.

- Very solid and reliable

Both on corporate networks and personal accounts, it works flawlessly each time. It’s fairly fast, although it could still use some speeding up, and works well with iPhone notification settings.

- Great

Does what it needs to do.

- Your Lover

This app is awesome for two factor authentication. It’s so fast. Like when I click on yes while authenticating, in a second it redirects me on my laptop. It’s awesome. It is definitely better than amazon’s two factor authentication which may take up-to 4-5 seconds. I know it’s not that long. But definitely this is super fast.

- MFA done well

Does the job well. I especially love the Apple Watch integration!

- Garbage app

No customer service if you don’t pay, terrible

- Worst thing

Code isn’t working and now can’t log back in my account

- Superb way to authenticate

Easy to use and reliable app for authenticating to a great variety of services. Definitely better than the competition and I wish those proprietary 2FA linked with a single product would also allow Duo Mobile.

- So bad, so underdeveloped

When it doesn’t work, error msgs are cryptic. Even account managers don’t know why the hell it doesn’t work. I hate it that it is forced on us with predatory contracts with the University of Waterloo. There should be a class action lawsuit against it.

- 3 stars

Fast, but inconvenient when phone is not in range

- Disregard negative reviews - AMAZING APP

The low reviews seem to be students complaining that they are forced to use this app. This is by far the best 2FA app out there. The rest feel archaic in comparison :)

- Why does this exist?

Google Authenticator already exists and is used by everybody. No reason to have 2 apps with identical features. Plus this near-spyware “evaluates” your device’s security level

- Students are ignorant + whiny

This app is fine. It’s not Duo’s fault if your school is doing a good job to protect you, but you don’t understand that or appreciate it. It’s not their fault if you enabled something on Instagram that you don’t understand, either. Go educate yourself. Don’t blame the devs for your problems. There are security exploits for text MFA, by the way, so no, not allowing them is not “old school”; it’s good practice. Finish your degree at U Waterloo and you’ll hopefully understand why.

- It works great

Yeah I honestly don’t understand why students are complaining so much. Props the devs, it’s an easy app. It’s easy enough that I don’t have to type of a review complaining about how this app has ruined my life

- Great 2FA app

Does exactly what it advertises and works nicely even in low coverage areas. The back end admin panel is easy to use and set up users. Shame this app has so many negative reviews from users who only rate this because their organizations enforce good security practices.

- Codes will not work

Hello everyone reading this, DO NOT GET THIS APP! The codes that it gives me will not work and now i am logged out of my instagram forever. Very poor app and i think it should be deleted from the app store.

- Is it really necessary for us to download an app?

Pretty convenient with the push notifications. No need for a text message with a code, just swipe down the notification than hit approve. But is it really necessary to download an app for this? Google has let me reset my password on the basis I’ve used the device before, so why can’t Waterloo do the same?

- Very poorly built

Keeps asking me to do a duo push when I checked off remember for 30 days. Even when I enable cookies on my iPad it still doesn’t recognize that so they probably need to fix that up.

- Does what a 2FA app should do

It is a 2FA app that allows me to authenticate by notification directly. Does exactly what it says it should and does it well.

- Great 2FA solution

Love the app: simple, practical and beautiful.

- Don’t get this

I had to get it to access bank info from university of Waterloo. Now it pops up EVERY SINGLE TIME and I can’t figure out how to disable it.

- Stupid

There’s no way to access my account once you’ve used all telephone credit.

- I can log back into my Snapchat

Okay so basically I can’t log into my Snapchat account and I can’t find my recovery code. If only you guys could actually be smart and have upgrade y’all’s system by giving us a second chance. Now I can’t log back into my Snapchat account 😐

- Awesome 2FA for healthcare

I just connected a healthcare worker for remote access. Really well done! Bonus points for “approve” notification on Apple Watch. I am assuming the “create account” option will store the 2FA’s in Duo’s encrypted cloud, just in case a restore is required due to lost/replacement phone. The negative reviews from the students are but a reflection of their ignorance regarding security, very often coupled with poor passwords Keep up the good work. #staysafe

- Jesus Christ

This app is so incredibly annoying. It’s things like this that make me wonder, why go on?

- Why UWaterloo??

This app is super annoying and quite frankly I dont see the point of using this. If your that worried about security then maybe dont hire an outsource company to do simple tasks

- Worst

Absolute crap, so stupid

- Are you kidding me?

I can’t express how angry it made me to have to download an app just for two-factor authentication.

- Works great

Don’t get why people gave the app low reviews! It’s doing what it’s supposed to do with no issues.

- Get rid of this app


- so extra


- 被迫下载


- Duo

Protecting my information, and ensuring that my account is safe is important to me. Thanks DUO!

- Worst app ever

Stay far away. Do not use this service. Dozens of better services out there. 1/5 is too high, Where is the 0/5 option??? Stay far far away. Youve been warned


THIS APP GAVE ME THE SCARE OF MY LIFE. I casually disabled my account because I needed a "pause". When I tried to log back but It would consistently tell me that the code is INVALID. I starting panicking! because guess what? I couldn't find the screenshot of my recovery codes either. THANKS GOD FOR ICLOUD. After some research I found out that the duo app couldn't connect to my account because it was disabled. This is a MAJOR BUG in your app and as I can see, many people have been in similar situations as me and yall still ain't fix it. Never thought having two-factor authentication would turn into such a nightmare. TRASH, I repeat. TRASH.

- Aidez-moi

J’avais fait un capture d’écran de code de récupération comme avais donné pour mon compte Instagram mais je les ai tous essayé ça marche pas je sais de me connecter à mon compte Instagram mais ça me demande toujours un code est-ce que vous pouvez m’aider à récupérer mon compte Instagram et récupérer le code de récupération parce qu’il marche pas ce que je fais des captures d’écran de çu

- Horrible

Lost my Instagram account cause it’s giving the wrong codes

- Nope

No god plz

- Absolute Nightmare

Switching devices is a hopeless endeavour. The cloud backups simply don’t work.

- Can’t login to Snapchat due to the code

I downloaded duo a while ago and the deleted the app and now i am trying to get into my Snapchat and it is asking for the code and I download duo again and it won’t show me any code This app is stupid and not recommended it to anyone you will lose your account

- Frustrating to get old accounts on new phone

Have to use this app for work. Got a new phone recently and can’t restore my work accounts through my phone. Have to do it through a backup system. Had to bring my old phone to work with me for a week just so that I could sign in to my accounts. Not to mention the instructions they provide on how to restore accounts are confusing and not user friendly. Overall very frustrating. Would not recommend unless required by work.

- Just fine

This app is just fine. It does the job, I’ve transferred phones and upgraded iOS and all that jazz. People leaving one star reviews are just plain incompetent. This app performs quickly, accurately, and the added bonus of approving from the Apple Watch pop up definitely makes it 5 stars. Stop listening to people who hate 2FA and actually read the reviews about the APP!

- Works Flawlessly

Frankly, I had some trepidation when my university implemented Duo based on the reviews here. I’ve been using it for over a month now and it’s worked perfectly. And it’s easier than other 2FA processes. I’ve authenticated access to my iPhone, iPad, a Mac and a PC. Perfect and easy every time. If you have a beef with your employer or university because they require 2FA, don’t take it out on Duo.

- Don’t listen to the negative reviews

This app works perfectly fine. I’ve been using it for years without issue. Those who have submitted negative reviews clearly don’t understand how to use two factor authentication, and have locked themselves out of their various accounts because of poor password management and a lack of attention.

- Apple Watch no longer receiving duo push notifications

With update to iOS 13 and watchOS on Apple Watch series 5, I am no longer getting Duo push notifications on my Apple Watch. This is refractory to restarting my Apple Watch, toggling Bluetooth on and off on iPhone, and checking notification settings in Watch app for Duo. Do not disturb is off on watch. iPhone screen is locked during duo push. I believe this will not be resolved until an update is released. Duo Pushes Work perfectly on my iPhone.

- Forced into this dumb system

University’s everywhere are getting this janky system, While traveling I couldn’t set this system up because I didn’t have service (I did have wifi) and my boyfriend failed a test because his phone broke and he couldn’t log in, even though his password was right, because all of a sudden we need “two-factor”. If this system allowed it to go through emails too or if schools had a 24 hour easy “forgot password or lost phone” option it would be fine but I hate this system and hope my school switches to something else soon.

- I’m locked out my Instagram

I have been locked out my Instagram for over 4 months because of y’all and can’t get back in I can’t find any methods to get it back I contacted everyone I even contacted Facebook and no one helps I make a new account because too much is on my instagram account that I need this app is a 0 star duo mobile doesn’t help you get your account back instead gives u a article that doesn’t help at all and the app is messed up I can’t even click recover account at the bottom but I can click everything else don’t get this app if you want to keep your accounts periodt

- What if your phone dies?

It works fine until your phone dies. If you ever have to login to something on your computer and don’t have your phone, you’re screwed. I don’t understand why they didn’t make a feature to compensate for that. I was trying to login to start a class when I realized I didn’t have my charger and my phone was dead, so I literally couldn’t get in. It’s so stupid. They could at least put an email option in in case emergencies happen with your phone.

- Not a great app

I have used this for school for about an year or so, but I really have had a difficult time. I am first of all thankful for the app developers who spent their time creating this app. I certainly could not make this app myself, but it seems the user experience is just not great. The app constantly requires you to update your phone to the newest operating system. I understand it’s for security purpose, but it can be frustrating. I have an Apple Watch and it has been difficult to receive notifications. However I appreciate that you can stay logged in for a day, but I wish they would access your location so you don’t have to login everyday from the same place. Maybe I don’t understand how the app works, but it seems if they revoked the daily password input and yet still have you just press a button from your phone. I don’t know tbh, but that was my honest opinion of this app.

- Easy to use. Great App.

I don’t know why there are so many 1 star reviews. This app works great. I use it every morning to two factor authenticate in for work and at least a few others times throughout the day on certain sites. I have the approval pushed to my Apple Watch and phone which makes the process fast, easy and seamless. No issues here!

- It Works as 2FA

It works as it’s supposed to work. Everyone seems to want to make everything so easy, but how much more easy can this app be. Quit crying about things that this app does, but you don’t know how to use them. There are multiple KB pages on how to use this. If this app is harder to use than your bank, then I would be worried about your banks security.

- Girl, don’t do it.

Ok, so I know there’s people in the reviews saying not to trust this app, but like don’t trust it especially if you are continuously getting hacked. My Instagram has been getting hacked over and over for the past three days and Instagram recommended I use this app. Well, I downloaded it and set it up and turned on notifications and it told me when someone tried to log into my account, it’ll notify me. Well this morning I got hacked again and they did nothing. That was the fifth time I had to change my password in the last 3 days. VERY disappointed. Next caller.

- Awful

I never write reviews but this app is so bad I needed to write one. I downloaded this app because my new school requires it. A couple weeks after I downloaded the app, I decided that I wanted to get a new phone. Now I can’t put my accounts onto my new phone and instead I have to keep my old phone near me to allow me access accounts that I NEED to use. I went onto the help page several times and they did not explain anything to help me. I’m very frustrated because I don’t want to carry my old phone around with me all the time because I never know when my 30 days is up.

- Works great

I’m one of many who recently had to start working from home for the first time. My company uses this and it works just fine. Usually the push approval request pops on my Apple Watch almost immediately, but sometimes I have to use my iPhone. Either way it seems to be a no fuss no muss method for 2-factor authentication.

- Terrible- Why are IT departments not reading the reviews?

Since downloading this app, I cannot properly access the school website app. 50% of the time. Even though, I have approved the school website through DUO; I still keep getting blocked and kicked off while doing work online. As an online distance learner; this is making my schooling untenable. I wish schools would rethink this app and look for something that actually works. DUO fix your issues. The reviews here are awful and DUO should not be promoting this to schools until they handle their technical issues.

- Great App!

Use it daily many times at work to do two step authentification to log into work accounts. Use it with my Apple watch. The issue I had with the App not working on my Apple watch is gone. Maybe some of the recent iOS updates helped. I take it. Thanks to the reply from the customer service.

- I despise this app

I DO NOT recommend this app. i would not recommend this app to my worst enemy. i have been logged out of my instagram account for 3 weeks. all because the codes from this horrible app will not work. i was hacked last year and instagram recommended this app to me for extra security. so i got it. it does not work. and it is confusing. nothing about it makes any sense. i have not heard back anything from instagram. i use this account for my job and now i’m screwed. so thank you! please do better. i wish i could give this zero stars.

- Mobile email access is failing

Accessing my email via desktop functions properly with DUO, but access to my email via my IPhone X is not working at all. I have even asked my University’s tech support to help me. As an Electrical and Computer Engineer, I do understand why this is great for security but most definitely this is not the most convenient implementation. I would not be surprised if a competitor surpasses DUO because of their lack of attentiveness to their customers and flaws. I just want to be be able to to conveniently access my school email via my IPhone again...

- Useless on Apple Watch.

What is the point when it cannot even recognize that the app is open on my iPhone? I had it for a moment, and then was trying to understand why it wasn’t able to connect. Now no matter how many times I open the app on my phone, the watch continues to show that no account is found. I have shut down the app multiple times on my phone. I have opened it from the home page and from the watch app. I have removed it from the watch and installed it again with no results. No help to be found at all.

- Add Naming Option

The app works well, just lacks a couple key features. The ability to add names to site codes, instead of just selecting "other" for third-party, needs to be added. Right now the only way to identify different websites (one not included in the preset list) is to add "website name" before the account name. You start to loose track of which codes belong to which sites. Also, the ability to manually sort is nice, however, multiple types of auto sort feature would be nice i.e.: sort by alphabetical, most recently used, *MOST OFTEN USED* etc. The ability to group multiple account logins under one website would be awesome! Like what you guys do. Works flawlessly so far. Keep up the good work and please keep these thoughts in mind for future updates 📳

- Love frustration and inconvenience? This is the app for you!

TL;DR avoid this garbage application at all costs. Anything linked to this app requires you to open the app and verify a push request (or manually type in a passcode). If you try to login to a website, say your university’s Blackboard from the uni library, and don’t have your phone, you’re screwed. You’d think upgrading your device would at least be excepted from this crap, right? Nope. In an age where you can hold your old phone next to your new one and have everything transfer over, this should be ez pz. Not for Duo Mobile! These cranks make you authenticate using your old device (factory reset and turned in for a rebate) in order to validate your new device. Now EVERY app or website linked to Duo is UNUSABLE. Their response? “Contact your [insert app / website helpdesk here] because we can’t and won’t do jack.”

- Straightforward

Straightforward app but I hate my university for forcing me to download this just to create an account. Who would even hack into my stupid account? What are they going to do, change my classes? This is only taking up space on my phone. If not forced to download this I don’t see why this would be that necessary, but if hypothetically I did think this was necessary it works.

- No Cloud Synchronization

This app doesn’t work when you are setting up a new iPhone from scratch and you don’t want to perform a restore from a backup option. The guides provided are outdated. At one point they mentioned went getting a new iPhone and installing this app you will get a prompt after RESTORING a welcome back window and a automatically reconnect option. If you are setting up your iPhone from scratch and you don’t want to restore from an iCloud or iTunes backup this app is not good. You will have to manually go over all your third party apps one by one and configure them. This was the solution given to me by their support team. Cisco you can do better than this. Please integrate in your settings a cloud backup solution to restore all third-party applications MFA for users who doesn’t want to restore their iOS devices from an iCloud or iTunes backup.

- I don’t get the negativity

I’ve been a mobile app developer professionally since 2013. What I go for is getting the user to what they need fast. This may not win UI of the year, but it’s an MFA tool and honestly, shiny animations would just slow it down. I’m guessing most complains are user error because this app is pretty spot on.

- Lost access to my account

I got a new phone and I’m not able to restore my duo app! How do they not ask for an email address when you first sign up? You manually have to enable the restore option and I wish I would of been aware of that. Also, their online information does not help. They should have clickable pictures and ways to easily understand what they are talking about. From an outsider point it’s difficult I’m bombarded with information and don’t know how to access that page they are talking about.

- Literal nightmare

My phone with all my duo information recently broke, and lucky enough for me my phone hadn't backed up since March. Since then it’s been literal hell on earth trying to get back into my Instagram account. I’m willing to pay any amount of money now to get back in, there must be options duo has incase something like this happens to get back into my account. I’ll verify my identity, talk to ANYONE, but I’ve been left completely on my own. I’m beginning to lose hope. I’m so desperate at this point, Instagram hasn’t gotten back to me yet. DUO PLEAE HELP ME.

- Security Check needs more work

I’ve updated my IOS to the latest version and Security Check is telling me I need to update. According to the last update, this issue was fixed but it is not. Please look into this. Otherwise it works as it should. The university I work for and the other I attend both use it with no problems.

- Review the app not 2FA

Most complaints I have read are about not wanting a 2FA layer added to their school accounts. That has nothing to do with the app. The app itself does what it needs to do gracefully and simply. It isn’t intrusive. I have worked with dozens and dozens of early resisters who now use it without issues.

- Best option for MFA and more

Best product available for MFA, but also provides fantastic single sign-on and native integration with countless cloud applications, and SAML2 for any cloud apps not listed. Provides a bit of endpoint compliancy testing. The cloud dashboard is AWESOME for troubleshooting. Not to mention the Duo Network Gateway to provide secure remote access to internal web and SSH resources.

- Never get this app

This app is soooo frustrating because once you sign up, there’s no way of getting rid of your account. If you delete an account from the app, instead of getting rid of the two factor authentication, it STILL asks for a passcode that you no longer have access to and so you can no longer access any account that you deleted!! I had a lot of problems with it and had to contact my university IT department for help. It’s terribly designed and I would never recommend this app to anyone!

- Can’t get old account

I’ve seen reviews about this already but there definitely should be an easier way to recover old accounts. I got a new phone and needed to use Duo but the app only gives me the option to add a new account and links an unhelpful article. Can’t I just have a Duo account to log into instead of having to re-add all my 2FA accounts bruh. And I seriously cannot find anywhere to enter my recovery password. Bruh.

- I hate having to use this it is entirely superfluous.

I check the little box that says to remember me for 30 days and yet 5 minutes later I need to open this annoying application and let my own phone know for the fifth time in a row that it is, in fact, still me.

- Couldn’t be easier

I find the negative reviews puzzling. Setup for me was a few minutes using my company’s instructions. Prompt on my phone is almost instantaneous. It’s a big green check mark and a red X. Even pops up as a banner. Much better than google authentication no complaints here.

- I hate this stupid app

If you ever get a new phone and want to move duo over it is the most impossible and backwards way to do it. Even after hours of trying I can’t get any of my accounts transferred to my new phone. I’m lucky enough to still have my old phone but any time I want to log into Instagram or my colleges website to do homework and tests I have to dig out my old phone. EVERY SINGLE TIME. And good luck if you don’t have access to your old device. Please for the love of god don’t get this app unless you have to!

- Apple Watch App Doesn’t Work

All I get is “No accounts found. Please open Duo Mobile on your phone.” I have Duo Mobile installed for my work VPN and it would be so handy if it actually worked on Apple Watch. App works fine on phone but all o get even after uninstalling and reinstalling the Watch app is the same message above. Trying to troubleshoot on their website leads to no useful information.

- This is the most annoying app

This app is terrible and serves no purpose. They prey on colleges and universities so that they can mine students data and the students get no say if they want to use this stupid app. I personally have a hardware token but of course if you happen to leave that in your office there is no way to access your account. I’m sure sooooooooooo many people are trying to hack into my account to pay my $150 in fees. Yes thank god I have this app. And the customer service is non existent. I would give zero stars if I could.


I love this app so much honestly I always had random hackers getting in to my Instagram and Snapchat account even when I had normal Instagram 2FA bro after getting this app everything is so secure and perfect but I want them to add more like Lyft cause honestly many people easily get in to Lyft accounts and Uber accounts

- Functional but brainless

The app works well, and so does the web push. A few apps that do not handle web 2factor just right may fail to display duo where okta, etc works, but it’s been a long time since I ran into that. The problem I have is that any time a timy IOS point release comes out, I have warnings that it is a major security issue and I need to fix it now. Even when the release notes say there are no security fixes, or when there are unrelated fixes. Duo, as a mindless policy, pushes you to be a guinea pig for very recently released cod changes, with no regard for potential lifecycle plans to the contrary. My device. My choice. Give us an option to turn off your nags, or set a delay for nags.

- Not compatible with ios screen time restrictions

Duo Mobile app works well with Edge or Chrome or any browser other than Safari unless you have screen time content and restrictions website set to unrestricted access. If website access is set to limited adult websites, duo mobile will not open to send the notice to your phone. It would be great if this was corrected.

- Needs to show authentication notifications on app icon

If you happen to miss the authentication notification and do not tap on it right away, you do not have a visual tip that there’s an authentication waiting to be approved. It would be great if you could add a circled number on the corner of the app logo showing awaiting authentications, the same way the built-in apps or Outlook app show the number of unread emails. Thank you!

- Locked Out !!!

the app is great but however this isn’t any account being made using this . I used duo to protect a couple of accounts . have the codes in my phone which broke and never turned on again so i got a new phone and couldn’t recover the codes or anything so i’m locked out of my most important things for my business . definitely need to write things down .

- I love you duo

Im sorry duo you dont deserve the hate youre getting 😭. It doesn't take long to set up at all, like 5 minutes or so. Now I'm more secure, and all I have to do for multifactor authentication is press a button on my phone after an alert pops up. Simple, easy, and my data is safer.

- “hacker” proof but not “life” proof app

An amazing 2FA app. (4A’s) but not life proof app. There are chances where an iCloud or iTunes backup will be missed. Otherwise a truly major app. *PRO TIP* check the developers FAQ on how to restore and backup copies before loading it with your favorite websites. If it’s still confusing... email them.

- Freedom.

This app finally allowed me to get my ex girlfriend off of my accounts after we had been broken up for a year and she was stilled logged into them and would criticize every time I followed or talked to someone else. I’d give this a million stars if I could. Thank you, Duo!

- Don’t get a new phone. It isn’t worth the trouble

Duo mobile works fine once you finally figure out how to set it up. But I recently got a new phone, and switching over my two factor authentication to this new phone was a nightmare. The app is absolutely terrible at walking you through that process and there isn’t any support line to call for help. So overall, disappointed in this app. Do not suggest.

- Please fix your app

My college recently started using this along with the regular passwords for our accounts and I’m locked out of my college email, I can’t schedule classes for next semester or pay for books. Nothing you app crashes every time I attempt to load it on my phone and even if I get it open the push. Notifications don’t get sent to the app in time and I have to restart it and than deal with the app crashing while trying to get onto my email.

- Just the Worst

My rage is indescribable when I log into my blackboard account on my phone, press send me a push, go to the app and approve, and then come back to see “session expired.” The last four times I’ve tried to log in it has done this, no matter if I send pushes, take calls, or try to enter codes. So now I’m writing a review for this terrible app instead of doing laundry. Too bad you probably have to use this app for work or school. If you have the choice to not get it, I say stay away

- Worst app ever

I never write reviews but this app is so bad I had to. My school gave us no choice about this and made us install this stupid app. And now I can’t log on to my school email and view my daily schedule on Outlook which I absolutely need to do multiple times a day on my phone. It requires me to pointlessly login in ever time and enter in a passcode from this DUO mobile app which never works. I didn’t need this extra layer of “security”, it’s more of an inconvenience if anything and doesn’t even work.

- Push stopped working in last iOS update

Update: Push is working now on my iPhone. Changing rating to 4 stars. Our university just switched to 2FA. Duo Push was working fine until last iOS update (14.2). Now I have to launch Duo manually and refresh to get 2FA to work. Needs to be fixed.

- Bug fix

It’s just for Some reason it just supports 3D Touch and not face ID and as far as I know I do not see an option to turn on face ID In settings or where ever you would turn it on as far as I’m aware of I can only use face ID to unlock my phone for 3D Touch to use for the app Notifications And I do not see an option for security check up at all
