Add recovery options to your administrator account
If you were granted administrator privileges to your Google Cloud account by another administrator, be sure to add a recovery phone number and email address to your account. That way, if you forget the password to your account, you can click the Need help? link on the sign-in page and we'll send you a new password via your choice of phone, text, or email. Until we have your recovery information, we won't be able to reset your administrator password via phone or email.
To add recovery information to your account:
Note: Administrator passwords can't be reset using phone and email methods for accounts with more than 3 super administrators or 500 users. If your account exceeds these limits, see these other ways to reset passwords.
