The authentication server waits. Your application sends a request. A secure handshake begins. This is Identity Management with OpenID Connect (OIDC) — the modern, standards-based way to control access, prove identity, and keep data locked to the right hands. It builds on OAuth 2.0, adds a clear identity layer, and delivers tokens that your services can trust without guesswork.
OpenID Connect works by issuing ID Tokens in JSON Web Token (JWT) format. These tokens contain verified user identity details, cryptographically signed by the Authorization Server. Clients validate them using the server’s public keys, ensuring every request comes from a known source. This process is simple to implement with libraries in most languages, yet powerful enough to run at global scale.
In identity management, OpenID Connect enables single sign-on, delegated access, and strong authentication without tying you to proprietary protocols. It supports common flows — Authorization Code Flow for server-side applications, Implicit Flow for browser-based clients, and Hybrid Flow for scenarios needing both ID and Access Tokens. The protocol is extensible, supports scopes for fine-grained permissions, and integrates seamlessly with existing OAuth2 infrastructure.
