1. A method for authentication on an appliance, the method comprising:
providing a certificate on a hardware security module from an authentication server, the certificate enabling a limited number N of authentication processes;
carrying out an authentication process on the appliance to authenticate a user on the appliance;
reducing the number N of authentication processes that are still possible for the certificate;
connecting the hardware security module to a computer unit by the user via an interface, and reducing the number N of authentication processes that are still possible by a counter of the hardware security module; and
requesting the certificate by the user and rejecting requests which do not meet a predetermined threshold of plausibility; and
authenticating the computer unit on the appliance, and enabling access to the certificate via a communication interface between the computer unit and the hardware security module; and
providing information relating to the appliance from the server together with the certificate.
