A system comprising a computer (PC) and an authentication device (TK), the authentication device (TK) comprises a mechanism by which the authentication device (TK) identifies itself to a computer (PC) as a native human interface device, comprises a mechanism to communicate with the computer (PC) as a native human interface device, and transmits to the computer (PC) authentication credentials in the manner of a native human interface device protocol;

• and
• the computer (PC) comprises a mechanism by which a program executing on the computer (PC) receives data from the authentication device using the native human interface device protocol thereby receiving authentication credentials from the authentication device.

A method to have a computer (PC) recognize an authentication device (TK), comprising operating the authentication device (TK) to identify itself to the computer (PC) as a native human interface device;

• operate the authentication device to transmit authentication credentials to the computer over the native human interface device protocol;
• and to operate the computer (PC) according to instructions of a program to receive authentication credentials from the authentication device (TK) over the native human interface device protocol.
