I had a related question: Is there any way to actually verify the logins of Wikimedia users w/o username/password?
See http://toolserver.org/~magnus/tusc.php. It verifies accounts by asking you to edit your talk page with a hash.
There is also an OAuth proposal: https://www.mediawiki.org/wiki/OAuth
