Overview
Authelia is an open-source authentication and authorization gateway that adds SSO and MFA in front of applications behind a reverse proxy.
Capability deep-dive
Lightweight SSO and MFA for reverse-proxied apps and a strong self-hosting community are the strengths. It is a gateway, not a full IdP, and there is no commercial support by default.
Pricing
Free and open source.
Bottom line
A popular self-hosted auth gateway for small teams and homelabs, not an enterprise IdP.
