1. A network-based access method operative in association with a first device of a user, and a second device of the user, comprising:

  • upon receipt of an indication that the second device is and remains in physical proximity to the first device that is presently locked, determining whether the user can be verified;

    wherein physical proximity of the second device to the first device is determined by the following sub-steps;

    determining whether a computed signal strength value is within a given range, the given range indicating that the presence of the second device is indeterminate;

    when it is determined that the computed signal strength value is within the given range, determining whether the computed signal strength value has a given first or second relationship with a prior computed signal strength value;

    when the computed signal strength value has the given first relationship, accepting the second device as being in physical proximity to the first device; and

    when the computed signal strength value has the given second relationship, accepting the second device as being not in physical proximity to the first device; and

    unlocking the first device automatically when the physical proximity is established and the user is verified.
