We recommend that you require users to change their passwords on a regular basis. Passwords can be set to automatically expire after a set number of days. You can override this
setting for individual users on their Login details screen (see Adding logon details).
Steps
Navigate to Account > Contacts.
Select a Password expiration limit setting. If you select No, passwords will never expire (not recommended). If you select Yes, a drop-down menu allows you
to set the number of days after which passwords will expire.
From the menu, select one of the following as the expiration period: 30, 60, 90, 120, 180 days, or Custom days. If you select Custom days, a new field
appears so you can enter any number of days you want. Periods of up to 720 days are now supported.
