1. A computer-implemented method, comprising:

  • storing, at a computing device including one or more processors, a first password and a first identifier at a memory of the computing device;

    receiving, at the computing device, a first request from a user to transition the computing device from a locked state to an unlocked state;

    scanning, at the computing device, a device via a short-range wireless communication medium to obtain a second identifier from the device; and

    transitioning, at the computing device, from the locked state to the unlocked state based on comparisons between (i) the first password stored at the memory and a second password input by the user via a user interface of the computing device and (ii) the first identifier stored at the memory and the second identifier obtained by scanning the device via the short-range wireless communication medium.
