Final answer:
In Unix-based systems, you can use the 'passwd' or 'chage' command to make passwords expire earlier. However, you need administrative permissions to do this, and you should inform users about it.
Explanation:
In Unix-based systems, such as Linux, you can use the passwd command to cause passwords to expire earlier. The chage utility is also used to view and change the password aging information. As an example, the command 'sudo chage -M 10 username' would set the password of 'username' to expire in 10 days.
However, please note that you need appropriate administrative permissions to execute these commands. Also, it's essential to inform any user whose password you're changing about this modification, to avoid confusion and potential access issues.
