Federated identity allows users to link identity information between accounts without centrally storing personal information. Also, users can control when and how their accounts and attributes are linked and shared between domains and Service Providers, allowing for greater control over their personal data. In practice, this means that users can be authenticated by one company or website and be recognized and delivered personalized content and services in other locations without having to re-authenticate or sign on with a separate username and password.
