1. A method for authenticating a communication partner on a device comprising a physical device implementation and a virtual device implementation, said method comprising:
receiving, by the virtual device implementation from the communication partner, an access authorization for the communication partner, said virtual device implementation being a digital twin of the physical device implementation;
inspecting, by the virtual device implementation, the access authorization; and
in response to the access authorization being deemed, from said inspecting, to be admissible, providing, by the physical device implementation to the communication partner, a credential that allows access, by the communication partner, to the physical device implementation,
wherein the credential is maintained only while a communication connection between the virtual device implementation and the communication partner exists.
