Rauthy
A lightweight, secure, and efficient open-source Identity Provider supporting OpenID Connect, OAuth 2.0, and PAM authentication.
What is Rauthy?
Rauthy is a lightweight, resource-efficient single sign-on (SSO) identity and access management solution built in Rust. It provides a secure OpenID Connect and OAuth 2.0 provider with modern authentication features like passkey-only accounts, designed to be simple to deploy and operate from low-resource hardware like Raspberry Pi to large-scale deployments.
Developers and system administrators needing a lightweight, secure identity provider for web applications, IoT projects, or centralized Linux/SSH authentication without the overhead of traditional solutions like Keycloak.
Developers choose Rauthy for its low memory footprint (often under 100MB), secure defaults like ed25519 token signing, built-in high availability, and unique features such as custom PAM/NSS modules for Linux system authentication and passkey-only accounts without consuming device storage slots.
