Why each option
A password history value of three means the system remembers the last three passwords, preventing a user from reusing any of them until three unique passwords have been used.
Password history enforcement stores a hash of previously used passwords; a value of three means the system retains the last three password hashes and rejects any new password that matches one of them, requiring three distinct passwords to be used before the original can be reused.
Password history tracks the number of unique passwords used, not a time duration; time-based password restrictions are governed by maximum password age settings.
Session timeout or re-authentication intervals are separate policies unrelated to password history; password history only controls password reuse.
Password history controls reuse prevention, not storage duration; passwords are stored as hashes in the policy database indefinitely up to the history count.
