Manual:$wgPasswordPolicy/pl

Szczegóły
A password policy is of the form

If the same check applies to a user via multiple groups, it will be applied with the  of the values. A fatal status means the password can't be used, even for login; a non-fatal error means the value is not accepted as a new password (on account creation or password change), but can be used for login; the user will be shown a (skippable) password change form. Default checks (found in ):
 * etc. are user groups, plus the special group  which is required to be present and applies to everyone.
 * etc. are arbitrary check names, defined in the  subarray.
 * etc. are policy values, passed to the appropriate callback defined in the  subarray.
 * Alternatively,  could be an array with the fields   (same as above),   (when set to true, users will be shown a password change form during login if the check fails) and   (like   but the form cannot be skipped).
 * etc. are PHP callables, which receive three arguments: the defined value, the object and the password, and return a StatusValue.
 * - Minimum length a user can set
 * - Passwords shorter than this will not be allowed to login, regardless if it is correct.
 * - Maximum length password a user is allowed to attempt. Prevents DoS attacks with pbkdf2.
 * - Password cannot match username
 * Your password must not appear within your username.
 * - Blacklists some passwords which have been used by MediaWiki unit tests in the past.
 * - Blacklist passwords which are known to be commonly chosen. Set to integer n to ban the top n passwords. If you want to ban all common passwords on file, use the  constant. See also  (the default file comes with MediaWiki and has 10K passwords).  Removed in MW 1.35+, use   instead.
 * - Same as the previous one, except uses the larger blacklist that comes with the wikimedia/password-blacklist library. Deprecated in MW 1.35+, use   instead.
 * - Password not in best practices list of 100,000 commonly used passwords.
