When a PIN need to use a protected device is manually entered for the time, it is encoded by means of unique identity number and stored in a PIN memory, the number is also used for the array in which or in connection with the device operates. If the user later identifies himself with an identity number which authorizes a subsequent use of the array, the encoded PIN stored in the PIN memory is decoded by means of the identity number and is made available to the device. Special advantages result when the environment is a vehicle and the device is a mobile telephone, since the network log-in takes place at the same time the vehicle is started with an authorized key.
