on a device’s management interface. You can specify a lockout period that must expire before
entering a fourth password after three incorrect passwords have been entered. You can also
force all administrators to periodically change their passwords in this screen. To open this
screen, click CNM System Setting in the menu bar and then click Configuration > User
Access in the navigation panel.
