To echo others, absolutely do not use Google SSO for anything you care about. Not just google, do not use any third party authentication (Google, Apple, Facebook, etc) on any account you want to retain. (Apple is perhaps a bit less bad than Google & Faceboook, but you can find horror stories of locked Apple accounts on HN as well.) When you do that, the account on the other site is tied to your google(apple/facebook/etc) account. If google(apple/facebook/etc) randomly decides to block your account one day for no reason then suddenly you're locked out not just from your google(apple/facebook/etc) account but from all unrelated accounts where you used their login. So password manager all the way, with unique accounts on every site (and strong long unique passwords of course). You'll also want to use an email address in a domain that you own, so you can't be locked out of that either.
