The invention discloses a multi-client uniform management method and system, being applied to at least one server side connected with the plurality of clients. Each server side correspondingly generates session information and stores the session information for each client logging into the server side, and the logged-in clients have operation permission for the server. The method comprises the following steps: intercepting a call request of a client specific to a server side, acquiring client information according to the call request, and inquiring corresponding session information in a storage space used for the storage in order to judge whether the client is already logged in or not; if so, calling the client to access to a predetermined graphical interface of the client with the operation permission in order to perform operations; and otherwise, allowing the client to log in by a uniform client login way, and calling the client to access the predetermined graphical interface of the client with the operation permission in order to perform operations. Through adoption of the multi-client uniform management method and system, uniform management and a uniform login way of accounts are realized, and problems in the prior art are solved.
