Abstract: An identity authentication method is described. The method includes, when receiving a group joining request that is sent by a first terminal and that is used for joining a trusted group, generating, by a server, a first certificate for the first terminal based on a first version number, and sending them to the first terminal. The method further includes, when determining that a second terminal is removed from the trusted group, updating the first version number to a second version number; and separately generating, by the server based on the second version number, a corresponding second certificate for a terminal not removed from the trusted group; and separately sending the corresponding second certificate and the second version number to the terminal not removed from the trusted group. In this way, during authentication, a terminal may compare a version number of the other party to perform identity authentication, thereby improving authentication efficiency.

Abstract: A login method, a token sending method, and a device related to the field of communications technologies include that a first terminal sends login request information to an application server of a first application. The login request information includes a login account username and a password for logging in to the application server. The first terminal receives a first token from the application server and that allows login to the application server. The first terminal sends the first token to a second terminal such the second terminal logs in to the application server using the first token.
