Currently MW shows userenames that are not present in the log. That could leak passwords to the log if the user did not safely hit the "tab" or klicks within the password field on login. In my wikilog I found an entry similar to this: 13:16, 28 June 2012 WikiSysop (Talk | contribs | block) Fehler beim Login (Der Benutzername „AnyusernameAnypassword“ ist nicht vorhanden. Bitte überprüfen Sie die Schreibweise.) IMHO it would be more safe to reflect something like: A User with IP xxx.xxx.xxx.xxx entered an unknown username.
MediaWiki does not log login attempts, successful or not. Aren't you using an extension to do this?
Oops, of course it is the UserLoginlog extension doing this. Sorry.....
