for those of you asking why: 1. If your G**gle account is compromised so are the accounts you used google to sign in to. 2. G**gle sees and keeps records of every app you sign into, which is just more data being fed to the company who primarily makes money from (your) user data for those of you asking what you should do instead: make an account with an email alias so if that email address gets compromised/leaked/sold you can just deactivate it and it doesnt link back to your main email address (proton.me/pass/aliases) for those of you asking how to check where you're signed in with G**gle and how to stop it: Go to myaccount.google.com/connect… (or Security → Your connections to third-party apps & services → See all connections). Filter for “Sign in with Google.” Select any site, then choose Stop using Sign in with Google to revoke access.
