I definitely think doing openid logins is way easier than any home rolled auth scheme.

Delegate responsibility where you can, which includes use authentication. It sucks that Persona died all those years ago because web browsers really could use an identity system for users to authenticate themselves against sites with their browser accounts.

The problem is then ofc getting browsers to cooperatively allow cross sign in. If messengers are anything to go by, siloed products really do not want to interoperate, particularly I imagine Edge and Safari.
