The obvious solution to this problem is to share session information across different domains. In fact, you want more: you want users who are already logged-in at domain X to be already logged-in at domain Y. Sooner or later web development teams face one problem: you have developed an application at domain X and now you want your new deployment at domain Y to use the same login information as the other domain. Below, we focus on this crucial aspect of a federated identity system. Its only concern is establishing the identity of the user and then sharing that information with each subsystem that requires the data. SSO is strictly related to the authentication part of a federated identity system. A federated identity system usually provides the means for administrators (or users) to handle accounts across domains or subsystems. Lastly, user management is related to the administration (creation, deletion, update) of user accounts. A federated identity system prevents data duplication by linking the related attributes. For instance, fields such as "real name" may be present in multiple systems. The attributes exchange aspect deals with data sharing across different user management systems. The authentication aspect deals with validating user credentials and establishing the identity of the user.Īuthorization is related to access restrictions (e.g., is the user allowed to access X resource?). Federated identity systems handle several concerns: The concept of a centralized or linked electronic identity is known as federated identity. In this post, we will study how SSO authentication is implemented for the web. With the number of websites and services rising, a centralized login system has become a necessity. Nowadays, almost every website requires some form of authentication to access its features and content. Single Sign-On (SSO) authentication is now required more than ever. #One key login full#Read the full report: Total Economic Impact of Auth0. Forrester Consulting analysis determines that using Auth0 can yield a 548% ROI and $3.7M in identity-related savings.
