Authentication method and device for heterogeneous module in system

The invention discloses an authentication method and device for a heterogeneous module in a system, which can be used in the financial field or other fields, and the method comprises the following steps: an auxiliary service module in the system receives an authentication request of a user, wherein the authentication request comprises authentication information of a main service module in the system; the auxiliary service module generates a verification request according to the authentication information and sends the verification request to the main service module, so that the main service module verifies the authentication information; and when verification success information which is sent by the main service module and corresponds to the verification request is received, the auxiliaryservice module determines that the authentication request is successfully authenticated. According to the invention, the beneficial effect that different modules of the authentication system in the system can be mutually auth
