Abstract

A device for password-protected accessing of a functional unit with a password input unit, which is designed for the entry of a password by a user, a password verification unit, which is connected downstream of the password input unit, and which is designed, preferably by means of an assigned password memory unit, for checking that the password entered is correct, and which is designed to activate the functional unit into a predetermined, first function operation on establishing a correctly entered password, the first function operation corresponding to an appropriate operation intended by the user, and the password verification unit having assigned to it a password generation unit, which is designed to create a first password as the correct password, the password generation unit being designed to create at least one second password, which on input by the user in the password input unit is recognized by the password verification unit as the second password, and the password verification unit, in response to recognition of the second password, is designed to initiate a second predetermined function operation of the functional unit, the second function operation being an operation that differs from an explicit error message or an error routine, which operation is different from the first function operation and does not correspond to the operation intended by the user.
