📋 Microsoft Entra Documentation Changes

 

Microsoft Entra ID supports two tenant configurations: A workforce configuration that's intended for internal use and manages employees and business guests, and a [customer configuration](/entra/external-id/customers/concept-supported-features-customers) which is optimized for isolating consumers and partners in a restricted external-facing directory. While the underlying identity service is identical for both tenant configurations, the sign in domains and token issuing authority for external tenants is different. This allows applications to keep workforce and external ID workflows separated if needed.

 

 

Every Microsoft Entra tenant publishes a standards-compliant well-known metadata document. This document contains information about the issuer name, the authentication and authorization endpoints, supported scopes and claims. For external tenants, the document is publicly available at: `https://{tenantname}.ciamlogin.com/{tenantid}/v2.0/.well-known/openid-configuration`. This endpoint returns an issuer value `https://{tenantid}.ciamlogin.com/{tenantid}/v2.0`.

 

 

Both access tokens and ID tokens contain header claims that provide information for token validation.
