OpenID Connect (OIDC) is a widely adopted standard for securely handling user authentication and obtaining identity information. This guide is designed to provide developers with a clear and practical introduction to OIDC.
Whether you’re new to the protocol or looking to refine your understanding, you’ll find explanations of key concepts, examples of common use cases, and details on how OIDC builds on OAuth 2.0 to enable secure, seamless user authentication for modern applications.
OpenID Connect (OIDC) allows applications and services to securely acquire tokens from a central authorization server, enabling access to protected resources.
Think of it like checking into a hotel: you authenticate at the front desk and receive a key (the access token) to access a specific room during your stay.
OpenID Connect (OIDC) is an identity layer on top of the OAuth 2.0 protocol. It enables applications to verify users’ identities and securely obtain basic profile information.
