password stored in the clipboard upon logging in using gamelauncher

If you highlight it sometimes it copies to clipboard.

^ That. I double click'd my user ID(to highlight all of it) when I used gamelauncher, to change between accounts, one time I ctrl+v'd to say something to a friend(that I was saying, but the had relogged, so I figured I'd copy+paste on my main, then relogged, too) and it ended up being my mule user ID on accident.
