OpenID Connect
OpenID Connect is an authentication protocol built on top of the OAuth 2.0 framework, designed for securely authenticating users and obtaining their basic profile information. It allows applications (called Relying Parties or Clients) to verify the identity of end-users based on authentication performed by an authorization server, as well as to obtain profile information about the end-user.
-
Authentication: Securely authenticates users across different applications and services.
-
Single Sign-On (SSO): Enables users to sign in once to access multiple applications without re-entering credentials.
-
Identity Tokens: Provides JSON Web Tokens (JWTs) containing user identity information, such as name and unique identifier.
-
Authorization: Authorizes access to protected resources based on user authentication.
