An external input method using the keypad of a user device and an apparatus thereof are provided to use a portable terminal as the input means of other information devices. The security authentication for a target device connected to a user device is performed(402). The user device receives platform information from the target device(404). The software code module of the user device corresponding to the platform is transmitted to the target device(412). If the software code module is installed in the target device, the user device transmits inputted text/figure command signals to the target device(414).
