Disclosed are a service locking method, apparatuses and systems thereof. The method includes: receiving a locking request including identification information of a designated service and an identifier of an operating terminal, the designated service being a service of performing a sensitive operation to network virtual property; and sending an authentication request containing the identification information of the designated service and the identifier of the operating terminal to an authentication server, and locking the designated service upon receiving successful authentication information from the authentication server. By locking the designated service in the operating terminal after the authentication server authenticates the operating terminal successfully, the problem that the network virtual property of a legal user is likely to undergo an unauthorized operation is solved; a designated service, once locked, may not be directly operated by any operating terminal, thereby preventing unauthorized operations on the designated service.
