## What it is
VoidAuth is an open-source single sign-on (SSO) and user management provider for self-hosted applications, acting as an OIDC provider, proxy ForwardAuth, and LDAP directory server. It supports passkeys, MFA, user invitations, self-registration, and email-based password reset, deployed via Docker with Postgres or SQLite storage.

## Use cases
- add single sign-on to my self-hosted apps
- self-hosted oidc provider
- forward auth for reverse proxy like caddy or traefik
- manage users and groups for homelab services
- enable passkey and mfa login for self-hosted services
- ldap server for self-hosted authentication
- invite users and allow self-registration behind sso

## When to choose
- you self-host multiple apps behind a reverse proxy and want centralized login
- you need an easy-to-deploy OIDC provider with passkeys and MFA
- you want user/group management with invitations and self-registration
- you need ForwardAuth or LDAP support in a homelab or small organization

## When to avoid
- you need enterprise SSO with SAML or SCIM provisioning
- you require a cloud-managed identity service rather than self-hosted
- you need massive-scale multi-tenant identity infrastructure
- you cannot run Docker or a database alongside your services
