"reset password" and then set your password instead using google single sign on.
And then remember not to use any single sign on service but generate separate passwords for every service and keep them in password manager you own.
Btw, the above works if you own the domain for your email, assumed yes since that was the whole point of Google for business. If not, buy own domain ASAP and switch to mail provider that allows custom domains.
- Migrate everything (that google will let you) off your Workspaces to somewhere else. (critical you move email first as gmail mail box will be deleted when you remove the license below)
- Upgrade to paid GSuite (its cool, you’ll cancel in a sec)
