Gluu oxd / Client API
The Gluu Client API, also called oxd, is a REST middleware application that simplifies and standardizes the process of integrating server-side web applications with a standard OpenID Provider. oxd is designed to work over the web (via https), making it possible for many apps across many servers to leverage a central service for OAuth 2.0 security.

Easy API for OAuth 2.0, OpenID Connect, and UMA 2.0
OpenID Connect is a simple identity layer on top of OAuth 2.0.
OpenID Connect enables a person to authorize the release of personal information from an “identity provider” to a separate application. In the process of authorizing the release of information, the person is authenticated
The oxd UMA APIs can be used to send a user to an UMA Authorization Server (AS) for access policy enforcement and are separated into two sections: UMA 2.0 Resource Server APIs and UMA 2.0 Client APIs.

API for user, group and FIDO device management
Another core component, this server provides the enrollment and authentication endpoints which enable people to use USB, bluetooth or platform FIDO credentials.
The heart of the Janssen Project, this is the server that provides the OpenID Connect and OAuth endpoints.
The configuration API is required to configure Jans Auth Server
