Example Command to Set Password Expiry:
This command ensures that the user will have to change their password every 90 days.
Block Password Repeats: Never let users type the same old passwords. This can be configured by modifying the /etc/pam.d/common-password file to enforce password history rules.
Implement Lockouts After Failed Attempts: To thwart brute-force attacks, you may want to implement account lockouts after failed attempts.
Sample Command:
Modify the /etc/security/faillock.conf file to implement lockouts.These best practices will help ensure that every Linux change password process you run works to make your systems more secure.
