20OIDC

20OIDC, or OpenID Connect 2.0, is an authentication protocol built on top of the OAuth 2.0 framework. It allows clients to verify the identity of end-users based on the authentication performed by an authorization server, as well as to obtain basic profile information about the end-user in an interoperable and REST-like manner. 20OIDC was developed by the OpenID Foundation and is designed to be simple to implement and use. It provides a secure and standardized way for users to authenticate to third-party applications using their existing credentials from an identity provider. The protocol supports various flows, including the authorization code flow, implicit flow, and hybrid flow, making it flexible for different use cases. 20OIDC also includes features such as dynamic client registration, token introspection, and user info endpoint, enhancing its functionality and security. The protocol is widely adopted in the industry and is supported by many identity providers and service providers. It is an essential component of modern authentication and authorization systems, enabling secure and seamless user experiences across different platforms and applications.
