Google has updated its Authenticator app for Android and iOS, the update is now available to download on both platforms and it brings some design changes and some new features to the app.

How to Add an Account to Google Authenticator You need two things: Google's authenticator app and a code from the account you want to add to the app (Facebook, Amazon, your bank, etc.).

Google Authenticator 5.0 should already be rolled out to everyone, but just in case it hasn't reached you, you can also download it from APKMirror.

How to take a backup of Google Authenticator Google Authenticator keeps your account safe with a time-based one-time password (TOTP). It stores the codes in the cloud for easy access.

The Google Authenticator app allows you to strengthen the Two-Factor Authentification on your phone -- for free.

Until now, Google Authenticator had an annoying flaw: Your one-time codes were stored only on your phone, which could cause a tremendous number of problems if you didn't have backup codes.
