+## About Microsoft APIs protected by Entra ID
+
+Microsoft have several well-known APIs that support OIDC (OpenID Connect) and OAuth2 for Authentication and Authorization, like Azure Resource Manager Rest API, Microsoft Graph API, KeyVault API to name a few.
+
+In addition you can create, expose and protect your own APIs via App Registrations, so there are a lot of usage scenarios.
