Server access authentication method and device

The present invention discloses a server access authentication method and device. The method comprises: receiving an access request sent by an intelligent terminal to the server through the application software, wherein the access request is used to request the service data to the server, the access request contains the first authentication information; comparing the first authentication information with the second authentication information pre-stored in the server; if the first authentication information and the second authentication information are consistent, allowing the intelligent terminal to access to the service data. The above method can greatly reduce the complexity of the authentication process and improve the efficiency of verification.
