Google Authenticator works with 2-Step Verification for your Google Account to provide an additional layer of security when signing in.

Features include: - Automatic setup via QR code - Support for multiple accounts - Support for time-based and counter-based code generation - Transfer accounts between devices via QR code To use Google Authenticator with Google, you need to enable 2-Step Verification on your Google Account.

  • Lost all of my codes with new version

    Good job, geniuses.
  • 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.
  • Barely half baked still!

    Sure I’m down with everything Cupertino but love all things Google as well! However, this Authenticator is still years behind others. Not only should they have already had dark mode in place when they had it in place with all the other apps they produce BUT THEY SHOULD HAVE THE ABILITY TO LOG IN FROM A DIFFERENT DEVICE AND ALL YOUR ACCOUNTS ARE THERE! I personally had an old device stolen from me and when I set up my new device I was screwed b\c all my 2FA numbers were on that old device. This *NEW* feature still doesn’t address this issue b\c you need THE OLD DEVICE! How’s that going to help me??! I still can’t get into my Dashlane Password Manager b\c that 2FA was linked to that stolen device’s Google Auth. I finally discovered Authy and haven’t looked back! It’s free and does every exact thing i want or need! Get on the ball Google!!!!
  • 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.
  • Junk Does Not Work

    By ugiuguhiuhugfiouji
    By the time you get around “I’m not a robot” your security number has changed. Anything that requires you to use Google software, you know will be bad. Why didn’t LifeLock use Norton’s VIP Access?
  • No features to export at all!

    By Alejandropf44
    Terrible app
  • The app is not launching

    By Alsubaiea
    For some reason the app is not launching any more. I tired to restart my iphone but still facing the same issue. Also I don’t want to delete the app and reinstall it to not lose the data in it. I’m in a bad situation now as i cannot login to my accounts. I have iphone 10 with 14.2 software.
  • 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
  • 3.1.0 crashes immediately on startup

    By chris_swenson
    All my TOTPs stored in the app are now worthless as the app crashes immediately for me. iPhone XS Max, iOS 14.2
