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.

  • Does what it does

    By Bemidji
    (Updating previous review.) reinstalled, and it now produces correct codes. Hmmm... still a serious flaw — no way to backup codes or copy them to another device unless you plan ahead to do that. I suppose there might be a way to get the code you need from the original issuer.
  • Apple Watch Support

    By TexAg76
    Please add support for this app to include the Apple Watch.
  • Simply doesn’t work.

    By secgiant
    I was forced to use this by multiple video game companies to sign in, and both times I was forced to contact support to bypass the authentication.
  • Doesn’t work

    By Dffghjjkkk
    I typed in the authentication code and my app says its invalid. POS...
  • Would be great to launch it from web browsers

    By ianlotinsky
    When I’m logging into Google from Chrome it would be great to tap something to launch this app instead of having to got to my home screen, find the right folder, find Authenticator, etc.
  • Almost perfect, but flawed.

    By gdawg0203
    I use this for all of my 2 factor apps. While every app/ account recommends this app, this app makes it difficult if the device is reset, replaced, or the app is deleted. Since this is a Google apps I’d love to see it be at least tied into a google account so restoring lost authentications can be less of a hassle.
  • Just use Authy

    By squalamack
    Authy has Touch/Face ID support, a watch app, cross-device synchronization, and a better and more updated UI. So use that instead. People who work at Google do.
  • Does not work

    By hot-wasabi
    Whatever I'm trying to authenticate always says these codes at not valid. There is no help in the app to fix this.
  • No backup

    By Gryzum
    Are you serious?!! This is one of the most important apps and it has no backup ?! After phone restore everything is lost.
  • Works at it should!

    By Busymomto5
    I’ve never had any issues with this app. Maybe all the complaints are from people who don’t know how to work it? It’s super easy use!
