Integrated second factor authentication

Abstract

Techniques and apparatuses are described that enable integrated second factor authentication. These techniques and apparatuses enable the improved security of something you have without the accompanying inconvenience or chance of loss. To do so, a secure physical entity is integrated within a computing device. While this provides the something you have without a need to carry a separate object with you, the something you have also must not be able to be accessed remotely. To prevent remote access physical wires are connected from the secure physical entity to physical structures on the computing device. In this way, a hacker or cyber thief cannot convince an authentication system that the cyber attacker does indeed have the something you have because to do so the attacker must be in physical possession of the computing device.
