Federated Authentication
With an enterprise identity management system, rather than having separate credentials for each system, a user will have a single digital identity to access all resources to which the user is entitled. Federated identity management extends this approach beyond the enterprise level, creating a trusted authority for digital identities across multiple organizations. In a federated system, participating organizations share identity attributes based on agreed-upon standards, facilitating authentication from other members of the federation and granting appropriate access to resources.
