Operating systems must enforce 24 hours/1 day as the minimum password lifetime.

| Description | ||||
| Enforcing a minimum password lifetime helps to prevent repeated password changes to defeat the password reuse or history enforcement requirement. If users are allowed to immediately and continually change their password, then the password could be repeatedly changed in a short period of time to defeat the organization's policy regarding password reuse. | ||||

$ sudo awk -F: '$4 < 1 {print $1 " " $4}' /etc/shadow
If any results are returned that are not associated with a system account, this is a finding.
