Obtaining a Google ID
A Google ID is a Google level resource required to create GCP and Terra accounts.
A Google ID is simply an email address. This email address must be either: a non Google email address that you have associated with a Google Account or a Gmail, Google Workspace (formerly G Suite), or Google Identity email address.
If you do not have a Google ID and wish to create one:
Register for a Gmail account or create an account with your non-Google email address.
To create a Google ID with a non-Google email address select “Use my current email address instead” on the signup form.
See Set up Terra account with non-Google email for additional instructions on how to create a Google account using a non-Google email address.
