What does federated ID management relate to in an SSO context?

Federated identity management in the context of single sign-on (SSO) refers to the establishment of a network of trust between different identity providers. This allows users to access resources across different systems and organizations using a single set of credentials.

In a federated identity model, organizations agree to trust each other's identity assertions. When a user logs in to one system, that system can then use a trust relationship with another system to grant access without requiring the user to log in again. This interoperability is crucial in SSO environments where users need seamless access to multiple applications and services that may be run by different organizations or even on different platforms.

This mechanism not only enhances user convenience by reducing the number of times they need to authenticate, but it also maintains security by allowing organizations to control and authenticate users within their own environment while still participating in a broader network of trusted identities.
