Hey!

I am wondering if is it possible to have different password hashes in MySQL database?

E.g.

Admin - SHA-256:Salt:Password User1 - MD5:Salt:Password

Have tried this:

UPDATE `user` SET user_password = CONCAT(':A:', MD5('somepass')) WHERE user_name = 'someuser';

And it changes the password correspondingly, but after one log in with the user it changes the hash back to SHA-256 (Guess some kind of MediaWiki default.

Any ideas?

Hi!

MediaWiki supports different password hashing algorithms. Even if one of these algorithms is set to be the default (SHA-256 in your case), for backwards compatibility it may still be possible to log in with hashes of another format. These older hashes are then updated during login. See Manual:User_table#user_password for more details!
