Google Authenticator works with 2-Step Verification for your Google Account to provide an additional layer of security when signing in. With 2-Step Verification, signing into your account will require both your password and a verification code you can generate with this app. Once configured, you can get verification codes without the need for a network or cellular connection. Features include: - Automatic setup via QR code - Support for multiple accounts - Support for time-based and counter-based code generation To use Google Authenticator, you need to enable 2-Step Verification on your Google Account.

  • Missing Names Bug in iPad Version

    By A n y M o u s e
    Google Authenticator iPhone shows the Name of the service (e.g. Google, Microsoft, etc.), your login identity, and the 6-digit code. Google Authenticator iPad only shows your login identity and code but not the Name of the service. This makes it difficult to know which code to use if your login identity is the same across multiple services, such as the many people who use their email as their login identity for many of the services they use.

  • Google shouldn’t be making these mistakes

    Absolute nightmare if you’re switching phones, locks you out of all your accounts and takes 48 hours minimum to reset
  • No transfers or restore

    By DSMART2003
    I have this app on another iphone and it’s setup to backup via iCloud and when I do a restore on the new iPhone, this app has no accounts listed, so I have to resetup accounts backup but the issue is I’m going have to go through the resetup because I use this app on an iphone and ipad, so that they have the same codes and lists available on both devices I need to setup on both iPhone and ipad at the same time, since I don’t have my ipad with me currently with me right now, I have to do redo more then once, tho, and I have alot of accounts listed with this app, I wish the app would allow to add device use with accounts with 2-step verification without having to turn off and/or changing the code(s) of accounts for other devices. So this app developer might need to add a backup option to be used by a google account, so a restore can be done and won’t lose access to accounts to have been setup!!! PS: I don’t know why iCloud didn’t restore this app with all accounts listed. What a pain! 😡😤😭

    It fails way too much, supposedly because of time out of sync. To top that up, there’s no button to re-sync it!
  • Empty after device swap

    By Fguev
    App works fine until you upgrade to a new phone, if you do you will lose all your tokens, the app will be empty! I have other authenticator apps in my iphone and they kept the data, GA was the only one empty after an iphone upgrade. I deleted thiis app and started using Authy for all my tokens. GA ahould be able to automatically mantain an encrypted backup of its data in iCloud, like many other apps do.

    So I really like it for what it is, obviously you need to have your backup codes before you get a new phone or uninstall the app. It would be great if there was a version I could run on the Apple Watch though.
  • Setup too confusing

    I felt like I was in a revolving google door. Google app, google sign in via safari, can’t find the code, forget it
  • Dangerous app to use as your 1st 2FA

    By Rortiz77
    Most people who start don’t know this, but Google Authenticator does not let you see the ID that generates the code after it’s been setup. Meaning, you can’t back it up. If your phone is lost or wiped and you have not made a backup, your screwed. You’ll want to do this now if you have not already. 1. Open every single website you have a 2FA and start over with a new ID. 2. Back up that ID in a safe place like LastPass. 3. Use a different 2FA app like Authy.

    The only reason I have this app is for My Nintendo.
