About:
oauth2-proxy is a reverse proxy that provides authentication for web applications using OAuth 2.0 and OIDC providers. It integrates with providers like Google, GitHub, and Azure AD to secure services without modifying application code. The tool handles the authentication flow and passes user identity information to upstream applications via headers.
Key Features:
  • Supports multiple OAuth 2.0 providers (Google, GitHub, Azure, OIDC)
  • Zero code changes required for applications
  • Session management and cookie-based authentication
  • Email and group-based authorization
  • Flexible upstream routing
Use Cases:
  • Securing internal web applications and dashboards
  • Adding SSO to legacy applications
  • Protecting Kubernetes services and ingress
  • Unified authentication layer for microservices
Alternatives:
  • Keycloak – Full-featured identity and access management solution with more complexity
  • Authelia – Lightweight authentication portal with similar reverse proxy capabilities
