Federated identity management (FIM)
Federated Identity Management (FIM) is a system that allows users to access multiple applications or services across different organizations using a single set of credentials . Instead of maintaining separate login details for each service, users can authenticate once via a trusted identity provider and gain access to all connected systems. FIM enhances security and streamlines user experience, especially in ecosystems where multiple platforms, partners, or institutions need to work together—like universities, enterprises, or government agencies.
