    Abstract: Disclosed in embodiments of the present disclosure are an authentication method, an authentication apparatus, and an electronic device. A first workflow viewing request is sent to a service system, in a case that the service system returns first workflow data, the first workflow data can be displayed. While returning the first workflow data, the service system also returns first verification information. When a first operation needs to be executed on the first workflow data, whether the first operation is allowed to be executed can be determined by sending the first verification information to the service system. In this way, the service system can determine whether the first operation is allowed to be executed using the first verification information previously fed back to an execution body, and display an execution result of the first operation when the first operation is allowed to be executed.
