If you're traffic sniffing, you'll see the data whether it's GET or POST. The distinction becomes important for things like http proxies and things that log/remember URLs - it's somewhat bad form to leave a userid/password sitting right there in the browser 'recent URLS' list or in a logfile someplace.

If you're passing the data in the URL, at best it can be obfuscated and reversed fairly easily (unless you've got enough Javascript to pop open a dialog window and use an entered value as a salt for encrypting before transmission).

Yes, the proper thing to do here is a POST over https.

Personally, I'm surprised that a frikking *domain registrar* is that clueless about basic security (the *biggest* issue in what would otherwise be a pretty minor vulnerability).

Or maybe I'm not, actually.. I wonder what *else* they got wrong?
