  • Essential App, But No Cloud Backup

    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.
  • Do not use this app!

    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.

    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.
  • Finally!!!!!

    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?

    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

    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!

    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!
  • Bad Design

    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

    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.
  • Thank you for adding a search function!

    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.
