OIDC

• https://www.scottbrady91.com/OpenID-Connect/OpenID-Connect-Overview

OpenID Connect (OIDC) provides a simple identity layer on top of the OAuth 2.0 protocol, enabling Single Sign-On (SSO) and API access in one round trip. It brings the missing user authentication story and identity layer to OAuth.
