Disclosed herein are methods, apparatuses, and systems for remotely accessing cloud applications. In one embodiment, the method comprises receiving an access request of a requester, sent by a cloud server, requesting being accessed by a controlling party; establishing a secure channel with the cloud server based on the access request of the requester, sent by the cloud server, requesting being accessed by the controlling party; receiving, via the safety channel, a login key generated based on the access request of the requester sent by the cloud server; generating, based on the login key, a login request for logging into the requester and sending the login request to the cloud server; receiving mode information of a login success returned by the cloud server after the cloud server verifies the login request; and receiving current mode information of the requester pushed by the cloud server, and entering a remote access mode for the requester. The disclosed embodiments can solve the following problems: remote access is not possible between different operating systems; a request for remote access cannot be made between terminals; and wasting unnecessary resources on site traffic. In addition, the method also prevents the risk of password leakage during remote access.
