Methods for selectively capturing and replicating one-time password generator functionality from device to device

A method, carried out by a second communication device in a communication system that includes a first and second communication device and wherein the first communication device maintains one or more one-time password (OTP) tokens for authenticating access to a corresponding multiple accounts of a user, the method comprising:

• receiving, from the first communication device, a request to clone at least one selected token of the one or more OTP tokens maintained by the first communication device in time-synchronization with at least one authentication entity;
• coincident to the request, receiving state information associated with the at least one selected token;
• using the state information to generate OTP sequences corresponding to the at least one selected token in time-synchronization with said first communication device and said corresponding at least one authentication entity, 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 at least one selected token, the first communication device experiences a loss of synchronization of the at least one selected token:,
• receiving a message from the first communication device to request restoration of the OTP sequences corresponding to the at least one selected token;
• responsive to the request, sending said state information associated with the at least one selected token to the first communication device that will enable the first communication device to regenerate OTP sequences corresponding to the at least one selected token in time-synchronization with at least one corresponding authentication authority.

A method comprising:

• maintaining one or more one-time password (OTP) tokens resident on a first device for authenticating access to a corresponding one or more accounts of a user, the one or more OTP tokens being time-synchronized with a corresponding authentication entity and subject to loss of said time-synchronization;
• sending state information that will enable a second device to generate OTP sequences corresponding to at least one selected token of the one or more OTP tokens from the first device to the second device;
• and
• following said loss of time-synchronization of the at least one selected token resident on the first device, sending a message to the second device to request restoration of the OTP sequences corresponding to the at least one selected token and, responsive to the request, obtaining said state information from the second device that will enable the first device to regenerate OTP sequences corresponding to the at least one selected token in proper time-synchronization with the corresponding authentication entity and said second device.
