I honestly haven't had anyone needing to reset their password yet. In my particular case it's not really the end of the world if someone gets locked out, but I should probably think what I'd do in that case...

Let's be real. Most users reuse their password for everything anyway. Those that don't likely use a password manager of some sort.

I doubt that any site needs a profile picture. Even Twitter gives you a default if you don't want to set it.

The alternative we have is what we did before social was a thing. The Internet existed before Twitter. The very site we're on doesn't require a social pairing to sign up for it!
