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.

  • Locked out of exchange Acct

    By disenfranchised driver
    Ive been using Google’s Authenticator for a while with no problem to access my exchange website account. Then I had to get my phone restored. Little did I know my saved codes were also gone too. Now I’m trying to log into my exchange site account, but lo and behold my codes don’t show in the authenticator. At first I was extremely furious at the exchange site for having this cost of massive inconvenience for the sake of security. Then I realized it’s probably this app that should’ve warned us ahead of time that after a factory reset, all our codes will be gone. For the laymen user, we don’t have the time to read the fine print and learn about stuff like this, and if it’s very important it should be easily told to us. So I’m locked out of my Account for days, but hopefully my account won’t be gone forever. Never trusting this app again, and may try out that Authy app to see if it’s any better. Very frustrating...
  • Falta nueva versión

    Hace falta una nueva versión que contenga un Pin y autenticador de huella para poder ingresar a la App, para mayor seguridad. Cumple su función, pero hace falta una nueva versión. Saludos!
