Among other things, a method is described for the configuration of a communication device (10) as well as a communication device (10). In this method, a communication link (20) is created from the communication device (10) to an external configuration computer unit (30) and identification data (100), which are related to the communication device (10), are transmitted from the communication device (10) to the external configuration computer unit (30) for the purpose of authentication of the communication device (10), with chip card-related identification features (111) being transmitted as identification data (100), with the chip card-related identification features (111) being assigned to a chip card (11) for the identification thereof, and with the chip card (11) being assigned to the communication device (10), and, when authentication is successful, a configuration of the communication device (10) is carried out.
