Password length?

Hi. The documentation says:

Password length requirements
By default, the User plugin requires a minimum password length of 8 characters for all users when registering or changing their password. You can change this length requirement by going to backend and navigating to System > Users > User Settings. Inside the Registration tab, a Minimum password length field is provided, allowing you to increase or decrease this limit to your preferred length.

There are no fields on the registration tab that set the minimum number. But minimun length i find in config.php.
User model has rules. And validation has nothing to do with the config

 'password' => 'required:create|between:8,255|confirmed',

fields.yaml in settings model:

            type: radio
            tab: winter.user::lang.settings.activation_tab

User modal also has method :

public static function getMinPasswordLength()
    {
        return Config::get('winter.user::minPasswordLength', 8);
    }

use only on reset password and signin.

upd:
Sorry I didn't see beforeValidate method where change rules with minLength from config.
But its not work beacuse validation rules in onRegister method in Account component take rules from property, before beforeValidate.

If I'm wrong, I apologize

Start with the password rule in config.php and the User model's getMinPasswordLength method, then trace the Account component's onRegister rules and beforeValidate hook. Compare that flow with the fields.yaml settings definition and the documented registration setting. Done means the configured minimum password length, registration validation, and documentation agree.
