Identity Federation
Identity Federation allows users to authenticate with one identity provider and use that verified identity to access resources across different organizations without creating separate accounts.
❓ What is Identity Federation?
Identity Federation allows users to authenticate with one identity provider and use that verified identity to access resources across different organizations without creating separate accounts.
⚙️ How Does It Work?
Uses standards like SAML or OIDC. The user authenticates with their home IdP; the IdP issues an assertion that the service provider trusts as proof of identity.
📍 Where Is It Used?
B2B partnerships, university systems, government, multi-cloud environments, M&A integrations.
💡 Real-World Example
A consulting firm's employees use their company's Okta credentials to access a client's SharePoint via SAML federation — no separate accounts needed, the client never manages the consultants' passwords.
