Length rule
The Length rule rejects passwords that contain too few or too many characters. Longer passwords are generally stronger, so only specify a maximum password length if you must maintain password compatibility with a system that can't accept long passwords.
Select the Length checkbox to enable the Length rule.
Select the At least option if you want Password Policy Enforcer (PPE) to enforce a minimum password length. Select the minimum number of characters from the dropdown.
Select the No more than option if you want PPE to enforce a maximum password length. Select the maximum number of characters from the dropdown.
Select the Between option if you want PPE to enforce a minimum and maximum password length. Select the minimum number of characters from the first dropdown and the maximum from the second dropdown.
