In this mechanisms allow users to sign on only once and have their identities automatically verified by each application or service they want to access afterwards. There are many practical and secure single sign-on models even though it is of great importance to current distributed application. Many application architectures required the user to memorized and utilize a different set of credentials (e.g., username/password or tokens) for each application the user's wants permission. In this approach is not practical and not secure with the exponential growth in the number of applications and services a user has to access both inside corporative environments.
