A method, server and computer storage medium for logging in, the method includes: receiving a login request including user's identification; assigning a body identification corresponding to the user's identification according to the login request, and generating a success login message that includes the body identification; returning the success login message including the body identification. The method distributes a corresponding body identification after receiving a login request that includes user's identifications, then returns a success login message containing the body identification to the client. When a same user's identification logs in different terminal clients, corresponding body identifications are distributed to every client, thereby the same user's identification can log in different terminal clients simultaneously without forcing other user's identifications which have logged in other terminals to be logged out.
