Which term defines a list of previously used passwords to prevent reuse?

• A. Password history
• B. Password reset process
• C. Password privacy
• D. Password expiration

Answer: (A)

Password history is the list of previously used passwords that the system stores to prevent reuse. By enforcing a password history, a policy requires that your new password isn’t among the last several passwords you’ve used, which helps avoid cycling back to old, potentially compromised credentials. The system typically keeps hashed representations of past passwords and checks any new choice against that history before allowing the change. This concept differs from a password reset process (how you recover access), password privacy (keeping your password secret), and password expiration (forcing a change after a time period), none of which specifically define the stored list used to prevent reusing old passwords.
