**APIs profiled:** 6

OpenID Connect (OIDC) is an identity layer built on top of OAuth 2.0 that enables clients to verify the identity of end-users based on authentication performed by an authorization server. It provides a standardized way to obtain basic profile information about users through RESTful endpoints including discovery, authorization, token, userinfo, and JWKS.
