---

TinyAuth is a self-hosted OpenID Connect (OIDC) provider that gives your apps a standards-based login system without bringing in a full identity platform.

It supports OAuth2/OIDC authorization code flows, PKCE, password login, passkeys, TOTP, social login, and a customizable multilingual frontend. Run it as a standalone server, ship it with Docker, or embed the server package in your own Node.js application.

Features

• OIDC/OAuth2 provider with authorization code flow, PKCE, discovery, token, userinfo, introspection, and revocation endpoints
• Multiple sign-in methods including password, passkeys/WebAuthn, GitHub, Google, Apple, and generic OAuth/OIDC providers
• Two-factor authentication with TOTP and passkey-based second factors
• Config-driven deployment through a single YAML file
• Customizable frontend with themes, branding, background images, language selection, and terms flows
• Database support for SQLite and PostgreSQL
• Standalone or embedded usage through Docker, the standalone CLI, or @tinyrack/tinyauth-server

Installation

Docker

  port: 8080

security:
  session_secret: change-me-session-secret
  hash_secret: change-me-hash-secret

database:
  type: sqlite
  path: ./data.db

basic_authentication_methods:
  password:
    enabled: true
  passkey:
    enabled: true

Start TinyAuth:
