1. A unitary mobile apparatus comprising:

  • a Bluetooth transceiver,whereby said unitary mobile apparatus can establish a secure two-way wireless connection with a second apparatus;

    whereby said unitary mobile apparatus stores user authentication credentials in a memory onboard said unitary mobile apparatus;

    whereby upon receipt of a first transformation directive from said second apparatus,if a drop in a Bluetooth signal between said second apparatus and said unitary mobile apparatus was not detected since the last time the user authentication credentials were transmitted to said second apparatus,said unitary mobile apparatus automatically encrypts the user authentication credentials using at least one first encryption function corresponding to said first transformation directive and transmits the encrypted user authentication credentials to said second apparatus wirelessly,whereby no pass code is requested, 

    wherein the at least one first encryption function is selected from the group consisting of symmetric key encryption function and asymmetric key encryption function; and

    if a drop in a Bluetooth signal between said second apparatus and said unitary mobile apparatus was detected since the last time the user authentication credentials were transmitted to said second apparatus,a pass code is requested.
