Disclosed is an authentication method of a dynamic two-dimension code instruction. A dynamic two-dimension code token comprises a collection module, a display module, an authentication module, an instruction module, a management module, a two-dimension code module and a control module. The control module, the management module, the authentication module, the instruction module and the two-dimension code module are integrated in the same microprocessor. The collection module is connected with the control module and the two-dimension code module. The display module is connected with the control module and the two-dimension code module. An authentication system of the dynamic two-dimension code instruction is the integration of service programs for carrying out the functions of authentication of the dynamic two-dimension code instruction, token synchronization, and management and configuration of relevant states of the token. The dynamic two-dimension code instruction has the characteristics of preventing exposure, being high in intensity, unpredictable, resistant to replay and disavowal, free of memory, accurate and efficient, and having physical isolation and bidirectional authentication, and safety of identity authentication is improved remarkably.
