• Google will never ask for your verification code or backup codes. If somebody contacts you asking for the code, don't give it to them, it's a scam.

  • If you did give them you code accidentally, then you should turn off two step verification, then reset it up, as this will reset the way the codes are generated, you should also revoke all trusted devices and reset your backup codes.
  Thanks
