Duo Mobile Comments & Reviews 2022

- 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.

- Fix it duo

Let me tell you a story.... in 2017, I went to a uni that required duo. The concept was great! Mind you, the uni was the administrative account and we the students were the users on the account. I added all my social media apps to this duo account. Fast forward to 2021, I haven’t been affiliated with the school in 3 years and they delete your email and account after one year. I finally bought a new phone, yes I had the same phone for years. I turned in my old phone to att & upgraded. I was updating all my social media apps on the new phone when I realized I couldn’t get into my duo app because it was a new phone. I tried to reset pws on the duo website and it said I wasn’t authorized due to my old uni being the administrator. I contacted the uni and they couldn’t send me a push because I didn’t have an account or even exist to them anymore! When I say ALL, ALL my memories are on my social media apps.... I was going to lose everything on there forever. Reaching out to the social media support desks are a waste of time, trust me I tried. The ONLY thing that saved me was going back to the att store and begging them to let me have my old phone back to back it up and unlink all my account from the duo app before backing up my new phone. Att is my savior for not sending out my old phone within 24 hours. Duo, I CAN’T be the only one with this story. DO BETTER!!!!!!!!!!!!!!

- Got a new phone, now I can't log onto my university account

This is the worst app I've ever used. Absolutely unnecessary and difficult. I've put up with it until now, but I can no longer sit silent. I recently got a new phone and in oder to reconnect duo to my university I need to log into my university account. But in order to log into my university account I need to verify it through duo. So obviously through this very dumb circle I can no longer log into my university account on my phone. Duo does offer verification though my old phone, but guess what? I no longer have that phone so it is absolutely impossible for me to verify my account through my old phone. I sincerely hope my university stops using this app as this is the worst experience I've ever had. All I want to do is be able to check my grades on my phone and I'll never be able to do that. And soon my 120 day access will run out on my labtop and I will no longer be able to access my school account which contains my grades, classroom, assignments, and more as I cannot verify my university account through duo. Making it virtually impossible to have access to my school account all because I got a new phone. This is the WORST app and experience I've ever had.

- 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.

- 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

- 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.

- 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.

- 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.

- 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.

- Duo is a scam

I understand the need for employers to use 2FA as a way to secure sensitive information yet I don’t understand the need for it in the school system. I have had to use it to see my classes, assignments, grades etc. and I failed a test all because I had lost my phone 2 days before and wasn’t able to do the authentication to access the test. I want someone to tell me who wants to steal my grades or see how I did on my history quiz. I don’t care if they hack into my grades, maybe they can make them better. At the beginning of the semester we were bombarded with emails saying we would be kicked out of the university if we did not register for this app. Seems a bit sketchy doesn’t it? This app has begun their warpath to a monopoly on online platforms used by businesses and schools

- 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.

- 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.

- Perfectly acceptable but nothing special

So many Authenticator apps in the store but they’re all basically the same. Nice design but like all the other apps it’s cumbersome when it comes to having a lot of accounts. Would like to see an app that gives me options to sync or save backups... most of all I’d like to be able to organize accounts into folders or categories. I have about 20 personal sites, 6 work accounts and 3 or 4 sites for accounts that I manage for clients. Across these groups I have multiple GitHub, gmail, okta, and other accounts and the only way to keep them separate is use multiple apps.

- 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!

- 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

- 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.

- 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.

- 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.

- 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.

- 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

- 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

- Still things to improve

Your website does not offer direct contact not involving enterprise admins so writing here. Please do not display banner notifications when the app is active already and incoming auth request comes, the notification banner just closes the button that responds to the request, and a user has to move the banner out first. Or move that button from the area covered by a banner to the center of a screen.

- 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.

- 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.

- Apple Watch Interface - Duo Mobile

While I LOVE the integrated function of being able to approve | deny requests on my watch I stead of digging my mobile out of my pocket - the watch interface should have the same side-by-side buttons available on the phone. Having the two thin lines one on top of the other has generated a couple of false deny claims due to hasty ‘fat finger’ responses. Square side-by-side buttons would make much easier targets and mimic the design from the mobile for app continuity.

- 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.

- 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.

- 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.

- 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.

- 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.

- 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.

- 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.

- 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.

- 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.

- App keep asking to set auto recovery password

Since the last updates in the beginning of the year, the app usually asks me to set up a recovery password, even though I have already setup. I then set it up as the app requested, later on I opened the app again and it asked again ... and I repeated the same steps. It has already more than 3 months since this issue occured. I have tried uninstalled and reinstalled the app but that did not work.

- The most terrible app as I had!

If you change your device or if you delete this app from your cell phone, or if you delete the other linked apps to this app, then it is impossible to restore your access to your previous DUO account and after that you will lose your access to those apps that you linked to DUO, never ever install this disgusting app to your phone, and I promise you if you use this app you feel regret very soon. The owners of this application should feel shame because of these reviews and this rate.

- 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…

- 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.

- Cannot Read Password

My telephone created a long recovery password in this application. I think it is for logging into Facebook. The reason for this application is unclear, except that Facebook and Google want to identify us, and take away our privacy one interruption at a time. Facebook made me join this application, by disabling my ads accounts. What is so ridiculous is that I couldn’t copy the password, because it was partially invisible. When I continued to the next page, I was notified that the application doesn’t keep your password. Make sure you remember it. Well, how can I remember it? I can’t even see it! Altogether a disappointing experience. Interruptive, slow, unclear, unfriendly.

- 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?!

- 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 ❤️

- 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.

- Wish I never ever used this product

Worst app ever it disabled my accounts without my knowledge and now I can not access my business pages on any of my devices. There is no one from duos side to help the worst descion ever using this app and not another company

- 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


Chinese spyware. How much did you pay Deakin Uni to use this dogpoo app?

- 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.

- 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?

- 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.

- Reconnect Automatically keeps getting disabled

Every 1-3 days my “Reconnect Automatically” setting gets disabled and I have to re-enable it and re-enter my password. I have usage data enabled, please fix!

- Ummm

Being forced to use this by the university...

- 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.

- 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.

- 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 :)

- 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 🤷🏾‍♂️

- 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

- 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

- Has never failed

This just works. We use in our Corp environment but also for other personal web services. Sad the comments are more about users being forced to use it rather than functionality of the app. Activation is super quick if IT knows how to implement properly.

- Slowing us down

Why has my organization forced us to use this? Took me 10 minutes to log in.

- M1 Mac compatibility coming soon?


- Good app, negative reviews are whiny people

App works flawlessly, and makes sense as an authentication app and is much more simple than the others I have used.

- Forcibly instilled by university

It's very inconvenient to use an app to login into course web page every time. Why don't they use SMS?

- Garbage

This app is garbage and is apparently supposed to ease your login process, but in reality it is broken. It’s asking me for a code that I never received and now I’m locked out. There’s no way for me to even receive a code through this app and now I have to contact my school

- How do I get help?

This app locked me out of my Instagram, and I deleted my Instagram off my DUO account and my Instagram still asks for this info. That I do not have. I can’t find a barcode & what is a key?? How do I get in contact with someone??

- Horrible

I have to do this for my YorkU account. The app is asking me for a barcode that I don’t have. When I press “no barcode” it asks me for a key. What’s a key?? If I go to my york account it just asks for an authentication method/code that I don’t have. Nothing works. Terrible app.

- Terrible app

I use this to generate passcodes. For some reason , Facebook was suddenly disabled. I couldn’t even restore it without a key from Facebook which I lost. Now I have to go back to Facebook to ask them to restore my Facebook account that I got locked out of. This is garbage!!

- not needed

such a hassle for uni

- Locked me out of Instagram

It worked fined until I changed my account username and password. Why do they make it so difficult to get your account back. Please tell me what a key is and where is mines for my account.

- Time is off by 30 seconds

Entered a key to test; countdown timer is about 20 seconds slower than my other two apps running the same account and key (1Password, Authy)

- Why is this Mandated for Uni Students?

Honestly, I’m sure this is a very good system in use for good reasons but to mandate this two factor authentication system for all students?? Once we’re out of lockdown and back on campuses, I know this will be a hassle to deal with as I often forget my phone at home and do not have access to data. These systems should not be mandatory.

- App is dog water

As per the title, developers of the app need to work on updates to make it more compatible with IOS software. Issue: often glitches where I can’t see the passcode needed and as a result I have to restart the app.

- works great!

app works great! nothing wrong with it. i am not sure if the whiny students with their negative reviews really understand the importance of security when it comes to passwords!

- Not a fan

York U is forcing us to download this app for two factor authentication. Pretty trash that there isn’t just a website or at least the option of a website for those that don’t have a phone or enough space to download an app just to be able to login to their university platform.

- Screw you

That is all

- Lovely

Very easy to use. The notification pops up within seconds, and I’m able to verify right away. I’m not sure why the rating is so low, but the app is fine.

- Disgusting

Should not have to download a third-party app for 2FA for my school. This company is definitely stealing data.

- Happy with it so far

The negative reviews for the app seem to be written by people who have no understanding of what dual factor authentication is and why it is important. I have had no issues with the app over the past year, it has done its job and I prefer the push style of authentication much more than SMS based or code generating token based methods.

- This app is actually great.

Really I can’t believe the reviews... They are really hurting this app. This is essential for proper security! Yes it’s inconvenient for you, that is 100% true. However, we need to be secure in this day and age. Thank you for developing such a nicely integrating system.

- Almost lost my account

I reset my phone a while ago and had a local backup on my laptop. When I restored from that backup all the codes on my duo app were gone and nowhere to be found. Somehow only an iCloud backup will work...? That’s risky as iCloud backs up behind the scenes and it’s not easy to check if you have actually backed up your codes. Definitely should’ve make it link to an important online account and have the codes stored there. Or even backup an encrypted file on iCloud drive. It would be much better to recover your codes. If you lose any of these it’d be hella difficult to retrieve them.

- The absolute worst

Been trying to get my Snapchat account back for over a year now Snapchat can’t help duomobile can’t help, this app is TRASH honestly..

- Works Great

I’ve used different types of Authenticator apps, i use this for work and I like it. Quickest one i’ve used yet no hassle to log in and works great!

- Lost my account

I use this for Instagram and I reset my password which logged me out of my account but then when I tried logging back in it prompted me to put in my code. When I went into the app it said that my account needed to be reconnected and I couldn’t do that due to me being logged out of my Instagram account. I contacted support and still haven’t gotten a answer back. I don’t think I can get my account back at all and it’s all because I couldn’t reconnect my account. Wouldn’t recommended. I’d really appreciate it if I could get an answer back from support.

- Works great but have a security flaw

Hi, I hope a developer sees this. Everything works great but on iOS devices with force touch, you can approve a DUO push request directly from the lock screen via the notifications screen without unlocking your phone, which I believe is a security concern. Please look into this, thank you. - a fellow software developer

- 3 stars

Fast, but inconvenient when phone is not in range

- Horrible


- 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.

- 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.

- 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.

- 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?

- 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.
