Google Authenticator

Google Authenticator enhances online account security by introducing a secondary verification step during sign-in.
This requires entering a code generated by the Google Authenticator app on your phone, in addition to your password.

The Google Authenticator app on your phone can generate verification codes without a network or cellular connection.

* Synchronize Authenticator codes with your Google Account across devices, ensuring access even if your phone is lost.
* Automatically set up Authenticator accounts using a QR code, a quick and easy process that ensures correct setup.
* Manage multiple accounts with the Authenticator app, eliminating the need to switch between apps during sign-in.
* Choose between time-based and counter-based code generation to suit your needs.
* Transfer accounts to new devices using a QR code, a convenient method for device changes.
