EASIE SSO: What It Is and Which Providers Support It

EASIE SSO is an OpenID Connect-based enterprise single sign-on solution that simplifies authentication by enrolling enterprises through their email domains against multi-tenant identity providers like Google Workspace and Microsoft Entra ID, without requiring per-customer credential exchanges. Created by Clerk, EASIE bridges the gap between consumer-grade sign-ins like "Sign in with Google" and complex SAML integrations by providing organization-wide, admin-mandated sign-ins with just-in-time provisioning and reactive deprovisioning. It is distinct from SAML, which involves complex XML-based setups and certificate exchanges for each customer, and from SCIM, which handles continuous directory syncing rather than authentication. EASIE is designed for enterprises seeking a streamlined SSO experience for users already on Google or Microsoft platforms, offering a simpler, more efficient alternative to traditional SSO methods while maintaining robust security through tenant verification and stable-identifier keying.
