What is federated identity management and what security challenge does it address?

Accepted Answer

Federated identity management allows users to authenticate once with a trusted identity provider and access resources across multiple organizations without managing separate credentials. This addresses the security challenge of reducing the number of passwords users need to remember and decreasing the risk of password-related vulnerabilities.
