Abstract: A multi-factor authentication technique can use multiple smart devices to determine whether a person is authenticated by minimizing the extent to which the person is expected to interact with his or her smart devices. In an example multi-factor authentication method comprises performing a first determination, that a first mobile device is located within a wireless range of a device, obtaining a unique identifier from the first mobile device, sending, to a server, the unique identifier, receiving, from the server, information that indicates a first authentication technique and a second authentication technique, performing a second determination that the person is authenticated by successfully performing the first authentication technique with the first mobile device and by successfully performing the second authentication technique with the second mobile device, and performing a final authentication operation in response to performing the second determination.
