Verification codes
Delivered to your phone or generated by the Google Authenticator App.
Six to eight digits (Example: 012345)
You don't have to remember it, because you can get a new verification code each time you need one.
You’ll need it every time you sign in unless you've marked a computer as "trusted"
Generate backup codes ahead of time and print them out, so you can use them as a backup if you don't have access to your phone
If you own an Android device, you can also generate codes through Google Settings, even if your device is offline.
