Any password, no matter how complex, can eventually be cracked. Therefore, Passwords must be changed periodically. If the operating system does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the operating system passwords could be compromised.
Solution
Configure noncompliant accounts to enforce a 60-day maximum password lifetime restriction using the following command, substituting in the username:
$ chage -M 60 [user]
