The verification code can be generated by the Google Authenticator app on your phone, even if you don't have a network or cellular connection.  
\* Sync your Authenticator codes to your Google Account and across your devices. This way, you can always access them even if you lose your phone.  
\* Set up your Authenticator accounts automatically with a QR code. This is quick and easy, and it helps to ensure that your codes are set up correctly.  
\* Support for 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.
