Patent attributes
A processing device comprises a processor coupled to a memory and is configured to establish secure communications with a plurality of user devices associated with a particular user, to generate an exclusive authentication token for utilization by each of the plurality of user devices in unlocking of secure functionality associated with that device, to provide the exclusive authentication token to only a subset of the plurality of user devices at a given time, and to force deauthentication of any of the plurality of user devices that do not currently have possession of the exclusive authentication token. These operations in some embodiments are performed by a deauthentication server implemented by the processing device. The processing device implementing the deauthentication server may comprise, for example, a remote server accessible to the plurality of user devices over a network, a smart watch or other wearable device of the user, or a user device.
