In a process for authenticating a user using a data station (16) in relation to a computer system (14) connected to the data station (16), a first value z is determined in the computer system (14) from an identification word (u) stored for the user in the computer system and a random number r generated in the computer system, and z a second value y is determined in the computer system (14) from the password a given by the user and the random number r. The password a is encoded before being sent to the computer system (14) and coded there by a one-way function (30). As a result of these measures, the password a does not appear in the clear text at any point in the data transmission.
