A computer technician needs to keep track of the last three passwords any employee has used. Which of the following best practices would the technician MOST likely use?

Password complexity enforces rules like requiring uppercase letters, numbers, and symbols, but it does not track previously used passwords.

Password history is a security policy that prevents users from reusing a certain number of their most recent passwords. By configuring a password history policy to remember the last three passwords, the technician ensures that employees must create a new, unique password each time they change it, thereby enhancing security.

Password length sets a minimum number of characters required for a password, but it does not prevent the reuse of old passwords.

A password manager helps users securely store and generate complex passwords, but it is a tool for end-users, not a system-level policy that enforces password history across an organization.
