Details

Specifies the maximal length of a user password.

It is not recommended to make this greater than the default, as it can allow DoS attacks by users setting really long passwords. In addition, this should not be lowered too much, as it enforces weak passwords.

Warning Warning: Unlike other password settings, user with passwords greater than the maximum will not be able to log in.

Since 1.26 deprecated in favor of $wgPasswordPolicy .
