## What it is
Rauthy is a lightweight, Rust-based Identity Provider offering Single Sign-On via OpenID Connect, OAuth 2, and PAM, with strong emphasis on Passkeys/WebAuthn and secure defaults. It runs standalone on Hiqlite (or Postgres), supports high availability, and includes an admin UI, events, and auditing.

## Use cases
- self-host an OpenID Connect identity provider
- add single sign-on to multiple applications
- replace Keycloak with a lightweight alternative
- enable passwordless login with passkeys and WebAuthn
- add MFA to user authentication
- issue JWTs for IoT devices and CLI tools
- manage users and clients with SCIM provisioning

## When to choose
- you want a simple, memory-efficient SSO provider with secure defaults
- you need passkey-first or passwordless authentication
- you want high availability without an external database dependency
- you need OIDC/OAuth2 for web apps, IoT, or headless CLI tools

## When to avoid
- you need deep ecosystem integrations or plugins available in mature IdPs like Keycloak
- your clients don't support modern token signing or PKCE and you want strict modern defaults
- you require LDAP as a primary user store
