So if someone forgets their login details, they&#x27;re basically screwed?  Because I&#x27;ve used some sites like that, and they&#x27;re a royal pain whenever something goes wrong. For example, TV Tropes didn&#x27;t used to have a password reset, so every time something went wrong, you&#x27;d pretty much have to either register a new account or bug someone on the forums about it.<p>Same with another site I was on, except the usual solution was seemingly &#x27;find one of the staff on another site they&#x27;re a member of and send them a message there&#x27;.  Made for a nice security hole too, since people could (and did) impersonate others and get given their accounts as a result.<p>You need some sort of email (or other contact information, like a phone number) simply so people can get their account details back in a semi secure way.
