Claim:
1. A system comprising: at least one processor; and a memory storing instructions that, when executed by the at least one processor, cause the system to perform: retrieving a first sensor signature associated with first set of sensor data of a first device in a first context, wherein the first device is a wearable device worn by a user: retrieving a second sensor signature associated with a second set of sensor data of a second device, wherein the second device is a mobile device; performing a first comparison by comparing the first sensor signature with the second sensor signature; determining a first comparison value based on the first comparison between a first sensor signature and the second sensor signature, wherein the sensor data relates to motion of the first device and the second device and is provided by at least one of a GPS sensor, an accelerometer, and a gyroscope; determining whether the first comparison value satisfies a first threshold based upon a similarity between the first set of sensor data associated with the first context and the second set of sensor data; determining the user should be authenticated on the second device based on satisfaction of the first threshold; and providing a password to the second device to authenticate the user on the second device in response to satisfaction of the first threshold; requesting a password for the second device when the first threshold is not satisfied; comparing the password for the second device provided in response to the request with a known password; updating the first threshold when it is determined that the password for the second device provided in response to the request for a password is correct; and causing the user to be automatically logged off the second device in response to the user taking off the wearable device.
