OpenID Connect (OIDC) is an authentication layer built on top of OAuth2, specifically designed for identity management. While OAuth2 focuses on authorization, granting access to resources via tokens, OIDC extends this by providing user authentication and returning user information through ID tokens.
In Angular applications, both protocols can be used for securing access. However, OIDC offers a more comprehensive solution as it handles both authentication and authorization. It simplifies the process by using a single sign-on (SSO) mechanism, allowing users to authenticate once and gain access to multiple services.
The main difference between OIDC and OAuth2 in Angular lies in their purpose: OAuth2 is primarily for authorizing access to protected resources, while OIDC adds user authentication capabilities. This makes OIDC better suited for Angular applications requiring secure user identification and SSO functionality.
