 OAuth2 Proxy is a flexible, open-source tool that can act as either a standalone reverse proxy or a middleware component integrated into existing reverse proxy or load balancer setups. It provides a simple and secure way to protect your web applications with OAuth2 / OIDC authentication. As a reverse proxy, it intercepts requests to your application and redirects users to an OAuth2 provider for authentication. As a middleware, it can be seamlessly integrated into your existing infrastructure to handle authentication for multiple applications.
 
-OAuth2 Proxy supports a lot of OAuth2 as well as OIDC providers. Either through a generic OIDC client or a specific implementation for Google, Microsoft Entra ID, GitHub, login.gov and others. Through specialised provider implementations oauth2-proxy can extract more details about the user like preferred usernames and groups. Those details can then be forwarded as HTTP headers to your upstream applications.
