Why anyone would use a Google app for authenticator anymore is a mystery to me. To use Google Authenticator with Google, you need to enable 2-Step Verification on your Google Account. This is a convenient way to move your accounts to a new device.


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.

Google Authenticator adds an extra layer of security to your online accounts by adding a second step of verification when you sign in.
