Features include:
- Automatic setup via QR code

Google Authenticator Reviews


Codes gone  Kydykn  1 star

Opened the app to find everything had been deleted. Now I’m locked out of my accounts... User be wary.


needs text search  ilya239  3 star

With many sites needing logins, scrolling to find the right code is frustrating. App needs incremental text search by site name. Also, ideally, add custom coloring and/or grouping to help find the right code. And as another review siggested, require touchid to see codes.


100% Broken, you WILL be forever locked out  Quagdarr  1 star

Every single Authenticator code will be deemed invalid. This does NOT have a settings feature inside the app to Sync time to fix the issue. Unsure how this occurred. Who missed adding in settings?? That’s like a contractor building a house and forgetting a bathroom and kitchen. Be warned!!!!!!!!!!!!! Google will destroy everything you have if you use this.

Great app  GhostsGB  5 star

App was great I use it to Authenticate everything it was awesome. 10/10


Please include search function  SebastianZhao  4 star

Good security app. But please please have search function and backup included. I have more than 50 secure accounted saved and it is almost impossible to find one on spot. Also the concern of losing my phone is killing me.


iPhone 6 to XS - No codes  Motoman11  1 star

Restored from iTunes backup and no codes have come through to my Authenticator app. How can I get my 2FA from my old phone. This was meant to work. No option to login at all on iOS version Help please !!!!


New device  Jacqui_666  1 star

I got a new phone and can’t set up this app again so it’s locked me out of my financial software!!!!

Yet another user name2

Backfired  Yet another user name2  1 star

After setting this up, I now feel less secure than I did before. I understand 2 factor authentication, but I don’t know what this app is doing. Why can’t you just text me a security code like everyone else? What is this manual entry thing? How exactly have you changed my account. Sorry, but this is the most unusable app I’ve ever seen from Google. I hate it.


Cannot remove codes no longer use  Reviewer543  1 star

I can rename codes I no longer use but cannot remove them. I should be able to remove them.


Useless if you change phones  TheForeverMan  1 star

This app is too simple for its own good. I say this because there seems to be no way to reconfigure it to my new phone from the old phone as the user interface gives no option at all. Bye bye Google Authenticator.

Painful experience to use for Xero book work Thanks ATO


Excellent  qwicc  5 star

Works excellent


No backuos  Matttail  1 star

I assumed the account were backed up, but when I moved to a new phone I lost everything. I'm now going through a very painful process to recover my accounts. Use any other app that includes backups. Duo, LastPass, Microsoft authenticator... Anything but this.


Having issues  Dee47410  2 star

I was once an android carrier until just today when I purchased my first IPhone. Had been using 2-factor authentication to log onto my Facebook acct, using the codes generated thru this app to complete the log in. Worked fine on my android, but with the IPhone the codes are not being accepted! Very frustrated because I am effectively locked out of my own Facebook acct! Help!!!


Want to get f-ed over?  Litisgod  1 star

This app isn’t supported by google. Lets say you get a new phone... all your codes magically disappear and you cannot retrieve them. Now, all the sites i used this 2fa generator will not let me in without lengthy exams that require hours, days of time waiting. Sometimes making it impossible to retrieve account access.


Mad🙄🙄🤬🤬  YSNMeqz  1 star

The codes didn’t work now I can’t sign into my epic games account


Serious flaw (no backups)  SeizeTheBeat  2 star

This app takes no cloud backups. I got a new phone and lost all my Authenticators I had stored. Spent weeks submitting paper work to get into my business accounts. I love google and their products, but this thing is an absolute joke. Even if your iPhone takes backups it will not restore the codes. Why is this not synced in a personal cloud or to google directly??? I suggest you use one that has an account sync, or one that’s integrated in a password manager (like 1Password’s “one-time password” feature). Google, I know you can do better than this.


Absolutely horrible  JwshBnkr  1 star

This app is absolute garbage, I can’t even get codes to play games I bought because it won’t get them. The app only gives me the codes I have from google from getting it set up on my pc to get help. If I could give this less than a star I would made this review destroy their ratings


Good app!  JoyousCaribou48  5 star

It was quick and easy! I tried using it on a older Samsung phone before but it didn’t work. It works fine on my current iPhone.


thanks for keeping this updated  wiwwowisp  5 star

ive been using this app for a very long time and its cool that it still works


Doesn’t work  SWIM9274728949945  1 star

Doesn’t work now I’m locked out of important things that I decided to depend on google for. Shaking my head as i write this. Pointing fingers as well.


Really good  oshaughnessy950  4 star

It’s really really good but the reason I rated 4 stars is because u need to make this available for the Apple Watch so i would be happy if it was available for that so plz make it available for the Apple Watch


Good  BananaCrusherPvp  5 star

Hated but fine


Lost access to accounts...twice  KcSembos  1 star

Get my accounts back, you sore losers!!! I can't access important accounts now thanks to the fact that your stupid app wiped clean the 2FA for them, twice!!!


All keys lost if device is replaced  kevpatts  1 star

This is a crucial app when used with business applications. Apple provide all the functionality to securely store the keys in the keychain but they are still lost to the app if you iOS device needs to be replaced. Poor integration.


What the frak!! Account wiped!!  blackdoe  1 star

What the frak Google, did you not perform upgrade testing on your software before releasing it, a basic necessity for all developers. What's the point in employing the worlds best and then pull an M$ type live beta trial. FFS!!!!

Update cleans history!  Donal Mulcahy  1 star

Updated this morning cleaned my stored accounts. Spent the last couple of hours trying to sorted it out. Also doesn't indicate differences between accounts if same email used. Please do not update until they sort this out


Lost codes  GreenCandy  1 star

Update lost all my codes! Good app though, needed an update.


Do not update  Tombrosa  1 star

I updated to the newest version, I never should do this: the authenticator whipes the accounts. Well done Google, I'm not able to access anymore.


Update reset  Toirneach  3 star

Updating clears all previous settings, locked me out with no authenticate, otherwise very handy little app


Good  RichT42  4 star
