Passwords for existing users must have a 60-day maximum password lifetime restriction in /etc/shadow.

Description

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.
