US Patent 9401905 Transferring soft token authentication capabilities to a new device

A technique transfers soft token authentication capabilities from an old device to a new device. The technique involves receiving a transfer initiation message from the old device while the old device is currently provisioned with the soft token authentication capabilities. The transfer initiation message includes new device binding information obtained by the old device from the new device. The technique further involves providing a reply message to the old device in response to the transfer initiation message. The reply message directs the old device to supply an authentication code to the new device, the authentication code being based on the new device binding information. The technique further involves receiving, from the new device, a provisioning message including the authentication code, and provisioning the new device with the soft token authentication capabilities in response to receipt of the provisioning message from the new device.
