Password history is a best practice that helps mitigate password reuse by preventing users from reusing previous passwords. This policy ensures that users must choose new, unique passwords after each reset, enhancing security by reducing the risk of password recycling.
A . Password length makes the password harder to guess but doesn't prevent reuse.
B . Password complexity ensures the password is harder to crack but also doesn't prevent reuse.
C . Password reset is the process of changing a password but doesn't control reuse unless combined with password history policies.
