Service that authenticates users and provides identity information to applications.
An Identity Provider (IdP) is a service that authenticates users and asserts their identity to applications. When users access applications configured for SSO, the application redirects to the IdP for authentication. After successful authentication, the IdP provides identity assertions that the application trusts. Microsoft Entra ID, Okta, and Google Workspace are common IdPs. Centralising authentication through an IdP improves security and simplifies user management.
Why It Matters
The DSC Perspective:
Your IdP is your identity authority. It controls access to all connected applications. Secure your IdP appropriately—it's a critical system. Consider IdP capabilities when selecting identity platforms.
