Thread:Project:Support desk/Database password is clear/reply

No there is not and it also would not make sense: At least at that point where MediaWiki wants to access the database, it must have the password in clear text. Basically everyone, who has access to LocalSettings.php, will also be able to edit the according PHP file, in which this database access happens so that he would get the password anyway.

What you however should do is this: Make sure that file and directory permissions in your wiki folder are tight enough. Especially for LocalSettings.php, permissions of 640 should be enough.
