You can control the behavior of security checks with options. Some options contain text fields that you can use to specify parameters. For example, the minimum number of non-alphabetic characters that is required in a password.
For example, in the Users to Check option of the Password Strength module, specify which users and security groups that all module security checks should examine or skip. This check is permanently enabled, as indicated by the circle in the box.
Modules and their associated checks can vary by operating system. Some modules have versions that run on all supported computers, though the checks differ by operating system, while others are limited to specific computers.
