User configuration: Security - Password management
Maximum password age defines how long a password is valid.
If you select the Prompt for password change setting here, you can select the desired length of time before a password expires that a
password warning appears in the Days drop-down list. After the selected time arrives, users will be requested to change their
password when they log on to the portal.
A deadline can also be set here to allow users to change their password after the old one expires for a certain length of time.
