Abstract:
1. A method, carried out by a first communication device that maintains one or more one-time password (OTP) tokens for authenticating access to a corresponding one or more accounts of a user, for selectively capturing and cloning selected tokens from the first communication device to a second communication device, the method comprising: selecting, responsive to user input, one or more of the OTP tokens resident on the first communication device and in time-synchronization with a corresponding authentication entity, yielding one or more selected tokens to be cloned; for each selected token, sending state information to the second communication device that will enable the second communication device to generate OTP sequences corresponding to the selected token in time-synchronization with said corresponding authentication entity and said first communication device, wherein some time after sending said state information to the second communication device that enables the second device to generate OTP sequences corresponding to the selected token, the first communication device experiences a loss of synchronization of the one or more selected tokens; after said loss of synchronization, sending a message to the second communication device to request restoration of the OTP sequences corresponding to the one or more selected tokens; responsive to the request, receiving said state information corresponding to the one or more selected tokens; and using said state information to restore the OTP sequences corresponding to the one or more selected tokens in proper time-synchronization with a corresponding authentication entity.
