acquiring, by a mobile electronic device, biometric information of a user of the mobile electronic device during a logging period;
determining, using the biometric information, a confidence value for an authenticity of the user by a computer system;
establishing, by an authentication unit, that the mobile electronic device is located in predetermined surroundings of an access-protected apparatus; and
approving or denying, by the authentication unit, access to the access-protected apparatus the confidence value;
wherein the authentication unit requests an active authentication when the confidence value is less than a predetermined minimum value, and
wherein an algorithm, reference data, or the algorithm and the reference data for determining the confidence value is adjusted by the computer system based on the biometric information if the active authentication is approved.
