Google Authenticator

Google Authenticator adds an extra layer of security to your online accounts by adding a second step of verification when you sign in. This means that in addition to your password, you'll also need to enter a code that is generated by the Google Authenticator app on your phone. Even if you don't have a network or cellular connection, the Google Authenticator app on your phone can generate the verification code.

* Sync your Authenticator codes to your Google Account and across your devices. This way, even if you lose your phone, you can always access them. * Use a QR code to automatically set up your Authenticator accounts. This is quick and simple, and it helps to make sure your codes are set up right. * Ability to handle multiple accounts. You can use the Authenticator app to manage multiple accounts, so you don't have to switch between apps every time you need to sign in.
