The length rule ensures that passwords contain the required number of characters.
Define a minimum length so that passwords must consist of at least a specified number of characters. Long passwords - seven or more characters - are usually stronger than short ones. With this setting, users cannot use blank passwords, and they have to create passwords that are a certain number of characters long.
