Parents
Love to spend the better part of an hour trying to get my dad back into his email account because Google decided to be a dick with Yahoo Mail accounts.
Also, my parents can't manage passwords for shit. I'd give them a fucking password manager if I could, but even if they could figure out how to use it, they'd forget the password to THAT.

not best practice, but their threat model probably doesn't include people breaking and entering to get access to their facebook account
