One feature pertains to a computing device that includes an input interface, a communication interface, and a processing circuit that is adapted to receive a request from an application to authorize an action and generate a dynamic access code associated with the action. The processing circuit also transmits a message to a secondary display device that includes information data associated with the action and the dynamic access code for display on a display of the secondary display device. The processing circuit authorizes the action received from the application if the dynamic access code is entered into the input interface. Multiple, unique dynamic codes may also be associated with different actions the application may make requests for, which are also transmitted to the secondary display device for display.
