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 Forgot password? link on the sign-in page and we'll send you a verification code via your choice of phone, text, or email. You can then reset your password to get back into your account.
Add recovery information to your account
You can use a phone number or email address to get back into your Google Account if you can't sign in. For details, go to Set up a recover phone number or email address.
