OpenID Connect

Last updated May 16, 2025, generated by Sumble

What is OpenID Connect?

OpenID Connect is an authentication layer on top of the OAuth 2.0 authorization framework. It allows clients to verify the identity of the end-user based on the authentication performed by an authorization server, as well as to obtain basic profile information about the end-user in an interoperable and REST-like manner. It's commonly used for Single Sign-On (SSO) implementations and to allow users to log in to different applications using their existing accounts (e.g., Google, Facebook, etc.).
