A system that allows users to access multiple applications with a single set of login credentials.
Description
In the context of Single Sign-On (SSO) protocols, federation refers to a framework that enables the sharing of user identity and authentication information across different security domains. This means that users can log in once and gain access to various applications or services without needing to authenticate separately for each one. Federation is crucial for organizations that operate in diverse environments, such as cloud services, partner integrations, and enterprise applications. It typically involves standards like SAML (Security Assertion Markup Language) or OAuth, which facilitate the secure exchange of authentication data. A practical example of federation can be seen in how Google accounts allow users to access third-party applications like YouTube, Gmail, and Google Drive seamlessly. This not only enhances user experience but also improves security by reducing the number of passwords users need to remember, thereby minimizing the risks of password-related breaches.
Examples
- Google Workspace allows users to log into various applications using their Google account.
- Microsoft Azure Active Directory enables users to access multiple services with a single sign-on experience.
Additional Information
- Federation can significantly reduce administrative overhead by simplifying user management across different platforms.
- It enhances security by centralizing authentication processes, making it easier to implement strong authentication measures.
