An authentication scheme in which an instance of a designated element is shifted to proximity with a designated target to gain access a device may be enhanced by creating conditions that allow for either the designated element or the designated target to be different for each instance of authentication. In one embodiment, a secondary display portion may be used to provide an indication of a dynamic designated element. In another embodiment, a secondary display portion, in combination with a tertiary display portion, may be used to provide an indication of a dynamic designated target.
