Cloud computing is one of today's most exciting technologies due to its ability to reduce cost associated with computing. This technology worldwide used to improve the business infrastructure and performance. At present cloud user authentication can be done by several ways like password authentication, Graphical and 3D password etc. In this paper I proposed the Advance Security frameworks in Cloud Computing Using Blowfish Algorithm. This Security Framework will provide Two times user authentication which will execute in different modules like user registration, user authentication, and password change.
