Thread:Project:Support desk/Can't Change Password Via phpMyAdmin!/reply (3)

$wgPasswordSalt defaults to TRUE, that's why I assumed that was the value in your case as well. So, if you have not changed it, you should really go with the algo I posted above. Btw. you should also be able to determine the value of $wgPasswordSalt by reading the passwords in the database: When they start with ":B:", they are salted; when they start with ":A:" they are not.
