A multi-functional device is attached to a secure network and includes a control circuit. The control circuit receives indications as to whether a user is authenticated to use the multi-functional device and in response, generates and sends a control signal to the multi-functional device. As long as the multi-functional device continues to receive the control signal, the multi-functional device remains in an operational mode to allow the authenticated user to access the multi-functional device functions. If the multi-functional device ceases to receive the control signal, the multi-functional device deactivates itself.
