Title

Users must be warned in advance of their passwords expiring. (Cat III impact)

Discussion

Creating strong passwords that can be remembered by users requires some thought. By giving the user advance warning, the user has time to construct a sufficiently strong password. This setting configures the system to display a warning to users telling them how many days are left before their password expires.

Check Content
