VoidAuth

VoidAuth is an open-source single sign-on provider for self-hosted applications. It sits in front of your apps and handles authentication and user management from one place, for both admins and end users.

• Unified access control: Manage users, groups, and access from a central admin panel.
• Standard protocols: Works as an OpenID Connect (OIDC) provider, a proxy ForwardAuth target, and an LDAP directory server.
• Account security: Supports multi-factor authentication, passkeys, passkey-only accounts, and encryption at rest with a Postgres or SQLite database.
• User onboarding: Invite users or let them self-register, with email verification for password resets.
• Customization: Set your own logo, title, theme color, and email templates.

VoidAuth runs alongside your existing reverse proxy, such as Caddy, Traefik, or nginx, so authentication stays on infrastructure you control.
