Administrators and Facility admins can force users to change passwords every six months. Navigate to Administration > System Management. Select the Settings tab and scroll down to Security Settings. Select the Require users to change the password every six months checkbox and click Apply.
TIP: A best practice is to sign in as user admin for setting up the system. Then after setup has been completed, each user should have a unique identity so that system usage can be traced back to a specific user.
