When a portable terminal of a user receives an authentication prompt message pushed by an application server, an authentication prompt option corresponding to the authentication prompt message is output at the portable terminal. A portal authentication is initiated after the authentication prompt option is selected by the user. MAC address information of the portable terminal returned by a portal server is acquired after the portal authentication is initiated. A user name and password for the application client terminal to log into the application server terminal is used as a user name and password for portal authentication. The MAC address information of the portable terminal returned by the portal server is sent to the application server. The present disclosure facilitates the operation of using the portal authentication, prevents the user from forgetting to perform the portal authentication, and brings convenience to those who are not familiar with the portal authentication mechanism.
