Understanding OIDC: The Key to Secure Authentication Explained

Executive Summary

OIDC, or OpenID Connect, is a powerful authentication standard built on the OAuth 2.0 framework, designed to securely share user details across applications. Unlike OAuth 2.0, which focuses on authorization, OIDC specializes in user authentication, allowing seamless logins to multiple services with consistent credentials. Understanding its core components, including OIDC providers and ID tokens, is essential for leveraging OIDC effectively in modern security strategies.
