Sign in with backup codes

If you can’t sign into your Google Account with your normal 2-Step Verification, you can use a backup code for the second step. Create backup codes to use in case you lose your phone, change your phone number, or otherwise can't get codes by text, call, or Google Authenticator.


  • To use backup codes, make sure 2-Step Verification is on.
  • After you use a backup code to sign in, that code becomes inactive.
  • You can get a new set of 10 backup codes whenever you want. When you create a new set of codes, the old set automatically becomes inactive.
  • Do not share your backup codes with anyone. Google never asks for a backup code other than at sign in.
