Yes, it can.

  1. You can set the minimum and maximum length of passwords using the settings found in “Plugin Options” -> “Main Settings”:

     

     

  2. Then, by adding a line similar to the following line to your wp-config.php file, you can specify any set of characters that you wish to allow:

    define(‘MBR_PASSWORD_BASE’, ‘ABCDEFGHabcdefgh01234*&^%$#@’);

    These characters will then be used when passwords are automatically generated by WordPress but will also be used to validate password changes entered by users.
