I'm against those kinds of rules. A rule implies that there are no exceptions. I don't think it would be right to ask someone who had a recent surgery to remove bandages from their face. I don't think it would be right to ask someone who covers their face for religious reasons to uncover.

I just don't think there needs to be a rule for this kind of thing.

Access to one's accounts already requires identification. If someone can identify themselves, then they should have access to their accounts.
