Authelia - The Single Sign-On Multi-Factor Authentication Server

•    Go

---

Authelia is an open-source authentication and authorization server providing two-factor authentication and single sign-on (SSO) for your applications via a web portal. It acts as a companion for reverse proxies like nginx, Traefik or HAProxy to let them know whether requests should either be allowed or redirected to Authelia's portal for authentication. Authelia works in combination with nginx, Traefik or HAProxy. It can be deployed on bare metal with Docker or on top of Kubernetes.

tut-spring-boot-oauth2 - Spring Boot and OAuth2:: A tutorial on "social" login and single sign on with Facebook and Github

•    Java

---

This guide shows you how to build a sample app doing various things with "social login" using OAuth2 and Spring Boot. It starts with a simple, single-provider single-sign on, and works up to a self-hosted OAuth2 Authorization Server with a choice of authentication providers (Facebook or Github). The samples are all single-page apps using Spring Boot and Spring OAuth on the back end. They also all use plain jQuery on the front end, but the changes needed to convert to a different JavaScript framework or to use server side rendering would be minimal. Because one of the samples is a full OAuth2 Authorization Server we have used the shim JAR which supports bridging from Spring Boot 2.0 to the old Spring Security OAuth2 library. The simpler samples could also be implemented using the native OAuth2 support in Spring Boot security features. The configuration is very similar.
