  • Essential App, But No Cloud Backup Dec 3, 2020

    By Proteus 846
    This is one of the most essential apps on my phone. I don’t know why I trust Google with my 2FA codes (I don’t really) but this is a very useful and important app. It is pretty basic as far as apps go, but it works for the intended purpose. They just added the ability to transfer 2FA codes when upgrading to a new phone. They released this feature less than a month after the second wave of new iPhones came out… so less than a month ago I did the transfer manually, turning 2FA off and back on for my new phone across a dozen services. Some were easy to transfer, others were the opposite. It took over an hour. Their timing with this feature is awful, but at least it’s here now I suppose.

    I have not had any technical issues;. Works every time. My only complaint is that there is no search/sort. Now that many websites offer 2FA, especially crypto, it's easy to rack up 20 accounts. Manually sorting is time consuming and a pain.
  • Finally!!!!! Dec 12, 2020

    By Review guy 467
    I just wanted to say Thank you for finally putting a export accounts option to move from device to device cause this was always my more preferred app but due to lack of exporting accounts couldn’t take the risk so I’ve been using the Microsoft version. I did like how there was a Apple Watch version although It was never really that useful anyway. But I hope maybe there might be a Apple Watch version of this someday if not that’s fine then. Please always keep improving this app.
  • Is this the update we’ve been waiting for? Dec 3, 2020

    By 2trot
    I saw with the most recent update Google added the feature to move accounts to a new device. Previously the Authenticator app only moved Google accounts so if it now moves all accounts that are stored in the Authenticator app that would make this app 100% more useful. I only change devices every few years so I’ll need to wait to confirm but this appears to be a major update with a feature that people have wanted for a very long time
  • Won’t start after iOS 14.2 update, v3.1.0 of the app Dec 3, 2020

    By philiaagape
    (UPDATE: it’s working again after app update! The App Store told me there was no update available when I first checked, but now 10 min later there is an update. Problem was Apple, not Google.) I have loved google Authenticator for my 2fa needs: SSH verification and websites. But now the app will not start. I’ve rebooted my phone and checked the App Store for updates but I’m running version 3.1.0 of the app already.
  • It’s alright... but they listened to my feedback and improved! Dec 8, 2020

    By iLangston
    The app doesn’t explain many of its features well and has noticeably less features than the versions on other phones. I sent a detailed feedback message about important features that were missing, and a few weeks later all the features I mentioned were either improved upon or added! It makes me happy that my input was listened to!

    I've always used it. Just be sure you export to another phone or device for safe keeping, to keep your life sane. 2 is 1 and 1 is none. I'm not certain what other methods of backing up you have without root. It's super simple, to choose what accounts/things you want to export/backup to another device, and takes literally seconds via qrcode. So do it before you ruin your life. You're a cow so act like a cow should.

    App works fine to its intended function. Only giving it a 3 star because there's no way to backup the data without exporting it another phone. I do wish they would add a backup feature syncing to your Google account then this'll be perfect. My advice to people is to don't rely solely on authenticators, write down the backup keys that the website provide to your accounts in case you lose or break your phone.
  • Thank you for adding a search function! Jun 23, 2021

    By leandroprz
    This was my review before the search was added: I have enabled 2FA in a lot of websites, sometimes is not easy to find the one I need by just scrolling through all of them. A search function would solve that.

  • Risky Choice for 2FA Dec 9, 2020

    By chopinrlz
    Using an authenticator app for 2FA is seen as a top choice for securing access to sensitive accounts over other methods. However, when the app stops loading, and instead crashes on open, you can easily lose access to these accounts if you’re relying on the app for 2FA and you don’t have backup methods configured (or physically accessible to you in the moment). This app is quite terrible in terms of its support and user experience. It did work, at one point, and now it doesn’t which means that I can never rely on it again. I’ve been slowing shifting to the Microsoft Authenticator app which has a superior user experience and feature set, is substantially more reliable, and works. I would not use this app if I were you.
  • Jul 12, 2021

    By Radox TheGreen
    Ok when it's working. When it suddenly decides to not work you have no access to your important accounts. You can't switch off the 2 step vf on most of those sites without it being authorised through the authenticator. But if the app isn't working you're screwed. Only help it gives is sync the time but if it's already in sync there's literally nothing you can do. Even reinstalling the app doesn't always clear up the problem. Why do so many sites insist on using this junk? Not fit for purpose.
  • Do not use this app! Feb 3, 2021

    By Doggettall
    If you are in a situation where you are forced to use this app, be sure to keep backup codes so that you can access whatever applications you need to access in the event you lose your connection with Google authenticator. Because of a recent Facebook debacle and not knowing that it was necessary to save recovery codes with Google authenticator, I am now unable to access a 10+ year old Facebook account that includes some business connections. Facebook‘s issues are on them however, since I have a long-standing Google account, I don’t understand how I am unable to recover the connection with my Facebook account to allow me to get back in again. Is google authenticator completely unaffiliated with Google? Very disappointing and in 2021, I can’t believe things are this difficult for the average every day user.
  • Jul 6, 2021

    By Zoey Wyllie
    NEVER use this app. While using the app you will probably find you won't have a single issue, which may confuse you as to why I have rated this as low as possible. The issue with google authenticator comes from the absolute negligence that came towards making the recovery/transfer system. The only way to move a code from one device to another is via an app on the QR code, so if you break your phone screen, lose your phone, need to factory reset, upgrade your phone, break your phone by accident etc, you will have lost all of your codes forever as you would be unable to scan the QR code! No sync for you own gmail account etc can be set up as it simply doesn't exist. So unless you are the least accident prone person on the planet and will never have any technicial problem in your life such needing to upgrade etc, then google authenticator is just a time bomb waiting to happen

    The appearance of the app should be improved. A recovery option should also be added when one changes devices due to force majeure. enable the option to be able to synchronize with the PC or with an extension in google chrome applying the aforementioned changes. If. Better access to the app with extra protection integrated into the types of security offered by the mobile.

    By Manuel Rodrigues
    Lacks search, sort and rename abilities which would be helpful to those of us who have many 2FA enabled accounts. Recommend, though not as secure, to save screenshots of all QR codes on a separate, non-internet connected device in case you lose access to your app via reset or loss. Use the screenshot to configure the authenticator to ensure that the screenshot of QR code works.
  • Jul 20, 2021

    By Brendan Byrne
    tl;dr Massive single point of failure trap that's easy to fall in. Do not use this! Save yourself the headache and use Authy instead. If your phone breaks and you didn't manage to save the magic QR code (which you have to manually generate no less) then you're completely screwed. Nothing Google support can do. You will lose the ability to generate codes for all your linked accounts. Hope you saved all your one-time codes because you're going to need to relink everything one at a time.
  • Jul 15, 2021

    By Yusuf Gbadegesin
    Good day. I used Google authenticator to lock three of my social media accounts, after which I had to reset my phone, but I currently don't can't gain access to those accounts, because it requires authentication from the app. On the app there's no option for password recovery or a means to get my old Google authenticator account back. Please I'll be glad if you can help me find solution to this problem. Thank you.
  • Bad Design May 29, 2021

    By John-Paul Neilston
    Google, just because you’re user base is FORCED to use this product doesn’t mean you should do the bare minimum. Did the developers think we would only need to store 10-20 accounts? One star review until there is a way to organize accounts by folder/category and export more than 10 accounts at a time. Come on! This is basic UI/UX stuff here. When you have a lot of accounts loaded it takes forever to find anything. And why would anyone only want to backup 10 accounts at a time? You should allow backup of All accounts or select accounts.
  • No Backups or Recovery methods Jul 7, 2021

    By Stoney Henge
    In 2021 it boggles my mind that there is no way to restore accounts added to this app. If you have to restore your phone for software issues or lose your phone then any account linked to this app is a total loss. You have to manually save backup codes for accounts or else they are lost. I have 2 other Authenticator apps that were able to restore accounts just fine. Terrible software by Google. Use ONLY if it’s the only option, other apps are much more user friendly.

    I loved this app until I had to factory reset my phone. I thought I had a word document with my backup codes, but I guess the document wasn't itself backed-up since I can't find it on Google docs. Now, it wants me to scan a QR code to re-establish the links to my accounts, but I can't do that since the QR code I would need to scan would be on the same phone that I am trying to get back into. I feel like Google has the ability to be better. Guess not.

You get tracked basically on everything you do. Support is weak and they don't get back to you or respond at all. I lost my phone and couldn't sign in any other way If you don't have the same device besides the one you used to sign up. Without your key which is a 12, 16, or 32 numbers password your assed out.

    I used to love this app in protecting my phone, but now they just locked me out of one of my favorite social medias. This app is bad at remembering the user based on either device or account they are on for the app itself. Once you either delete the app or have the app on another phone, you don't have your codes anymore. Then they'll suggest "Having a 2FA verification which honestly doesn't work. It doesn't restore your codes at all! Please fix this issue. I don't like this at all.

    An app or website that required the use of Two-FA. Being able to set up, reset or do anything other stare at it. I have all these wonderful options available to me if I could just follow the instructions. Which seems not work, no reset. No removal. If only money wasn't involved because then I would not have retry this every few weeks. In theory, App would be wonderful. If there tools, explanations and instructions. All those wonderful things. It's great to follow video as well.. till you get To the point of wow. 🤬

Normally we use such app to secure our accounts. but if something bad happens accidentally, you are DOOMED and no way out.. :(😢
