Authentication method and system, electronic equipment and readable storage medium

The invention provides an authentication method and system, an electronic device and a readable storage medium, a unified authentication system provides a function of binding a corresponding relationship between a business account and a user unique identifier (unified authentication identifier), so that a business system can obtain a business system account corresponding to the user unique identifier from a binding device, and therefore, the user experience is improved. Even if the service system does not use the unique identifier of the user, unified authentication can be carried out based on the unified authentication system. Therefore, the application range of unified authentication is widened. In some implementation modes, the binding device is constructed based on a Java environment and can run on machines in most environments. Moreover, the method does not depend on the unique identity of the user any more, but uses a user binding mode, and can be compatible with most systems, so that the method has hig
