OpenID Connect is an authentication layer built on top of the OAuth 2.0 protocol that allows users to log in to multiple applications using a single set of credentials.
Description
OpenID Connect is a widely adopted single sign-on (SSO) protocol that simplifies the user experience by allowing authentication across different services without needing multiple usernames and passwords. It enables users to log in to various websites and applications using their existing accounts from providers like Google, Facebook, or Microsoft. This is achieved through a standardized interface that securely communicates user identity information between the identity provider and the application requesting authentication. OpenID Connect enhances security by reducing password fatigue, minimizing the risk of phishing attacks, and enabling features like access tokens for secure API interactions. By using JSON Web Tokens (JWT), it provides a compact and self-contained way to transmit user identity information. As a result, developers can implement OpenID Connect to deliver seamless user experiences while maintaining strong security protocols.
Examples
- Google allows users to sign in to third-party applications using their Google account through OpenID Connect.
- Microsoft Azure Active Directory uses OpenID Connect to provide secure access to enterprise applications.
Additional Information
- OpenID Connect supports multiple authentication methods, including passwordless login and multi-factor authentication.
- It is widely used in modern web and mobile applications, enhancing user engagement and retaining customers.
