Description
Password complexity, or strength, is a measure of the effectiveness of a password in resisting guessing and brute-force attacks. To meet password policy requirements, passwords need to be changed at specific policy-based intervals. If the operating system allows the user to consecutively reuse their password when the password has exceeded its defined lifetime, the end result is a password that is not changed, per policy requirements.
