Configuration parameters
Each of the items in the $wgValidPasswords array can be set to require that item in the passwords for new accounts and password changes. With the exception of "minlength", if the item is set to "true", that item is required and "false" means that it is not required. The item "minlength" is set to $wgMinimalPasswordLength, which is set to the minimum character length requirement of the password (the value '0' means that there is no minimum requirement). The array $wgPasswordSpecialChars is used for the "special" item of the $wgValidPasswords array.
