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 password compatibility must be maintained with a system that cannot accept long passwords.
Select the Enabled check box to enable the Length rule.
Select the at least option to specify the minimum number of characters that passwords must contain. Choose the minimum number of characters from the drop-down list.
Select the no more than option to specify the maximum number of characters that passwords can contain. Choose the maximum number of characters from the drop-down list.
Select the between option to specify the minimum and maximum number of characters that passwords can contain. Choose the minimum number of characters from the first drop-down list, and the maximum from the second drop- down list.
