The usage and management of information technology resources and services are revolutionized with the arrival of Cloud Computing. But, the revolution always comes with problems. Authentication is one such problem. Especially for Graphical Password Authentication System, there is a threat of shoulder surfing attack. This research presents a multi-level graphical password authentication mechanism by extending an existing method. UGPSCCCT (User guided Graphical Password Scheme for Cloud using Caesar Cipher Technique) is the existing method and this method is extended in this paper such that another level of security is added. The user credentials in this method are transmitted to the server in encryption format. A key is generated for every login to encrypt user details. The analysis of the proposed method is done by calculating the computational cost and communication cost of the proposed method
