You can control the behavior of the security checks with options. Some options contain text fields where you can specify parameters such as the minimum number of non-alphabetic characters that is required in a password.
Other options are used to specify the entities that you want to examine as name lists. For example, in the Users to Check option of the Password Strength module, you specify which users and security groups you want all module security checks to examine or skip. This option is permanently enabled as indicated by the circle in the box.
To display the name lists, click an option or security check on the left side of the window. In the name lists that appear on the right side of the window, you can specify the items that are included or excluded when you run all or some of the security checks in the module.
