If you use a password manager (and my condolences to those who don't), there's really no benefit to using OAuth over an email sign up. It can prepopulate your personal information, but I usually don't want that for the services I sign up for.

There's a couple of services where I prefer to use github for sso because I need them to integrate with data stored there, and it makes sense to me to "bundle" those accounts. But that's very much an edge case.

Is this where I complain about companies that insist I install their MFA app rather than just letting me use Google Authenticator? You're not special.

Except for the really big one, which is strong MFA provided by the identity provider even when the site doesn't support it natively.
