Self-host Authelia on a VPS
SSO and 2FA gateway for your self-hosted apps.
Put one login and two-factor prompt in front of all your internal apps, with fine-grained access rules.
Why self-host Authelia?
Authelia means your self-hosted services are not individually exposed — one hardened gate protects them all.
How to install Authelia

Practical tips
- Give Authelia its own database user with rights only on its own schema.
- Reverse-proxy Authelia and terminate TLS at the proxy so certificates are managed in one place.
- Take a VPS snapshot before major upgrades so you can roll back cleanly.
- Keep Authelia patched — most self-hosting incidents are unpatched software.
