This would probably be a good place to suggest to others here to track which accounts you've logged into via Google or other social media oath.
I just had to log into stack overflow for the first time in years, and did not remember what I used to previously log in. Once I figured it out that information went into Keepass too.
You should assume Google, GitHub, and Apple are hostile and try to limit your blast radius. If you have an account problem they have no customer service to help you.
I can't get into my Google account that's almost 20 years old because I only have the username, password, recovery email and have all the email forwarded to me, but I no longer have the phone number and they silently enabled 2FA SMS at some point.
Yes, this is exactly why I won’t use these federated identity features of platforms like this. I have a reasonable amount of trust that they are mostly secure, but I have zero trust that they will be helpful if I ever have account troubles. What I don’t need is to have Google (etc) auth problems cascade down to every other account I own.
I really wish Bitwarden had more robust tools for organizing, sorting and tagging passwords. The current system of sorting them into folders is practically useless.
I track this in my password manager. Accounts where the YubiKey is enrolled are tagged "YubiKey (FIDO)".
