Apparatus for and method of multi-factor authentication among collaborating communication devices

摘要

Multi-factor authentication is enabled across a plurality of communication devices. A user performs authentication by using a first authentication factor on a first of the communication devices, and by using a second authentication factor on a second of the communication devices. A collaboration credential is shared among the devices to enable the devices to collaborate with each other. Both of the authentication factors are bound together. A multi-factor identification token is issued to each device, to support multi-factor authentication for the user across the devices.
