Authman: Cross-platform 2FA TOTP server with mobile and desktop apps
Authman is a self-hosted 2fa tool. Cross-platform 2FA TOTP server with mobile and desktop apps.
Why self-host Authman
When you deploy Authman yourself, you own the instance. That means no rate limits, no pricing changes, and no worry about the service shutting down.
What it does
Authman falls into the 2FA category of self-hosted software. It is designed to be deployed on your own infrastructure, whether that is a home server, a VPS, or a local machine running Docker.
Deployment
Docker is the most common deployment path. If you are already running containers at home, adding Authman to a compose file is a low-friction way to try it.
Alternatives
If Authman does not fit your needs, common alternatives include Authy, Google Authenticator. The self-hosted versions of these tools often differ in resource requirements and feature focus, so it is worth testing the one that matches your workload.
Maturity
The current release is 1.0.1. The project has moved past early development and tends to ship stable, documented releases.
License
It is licensed under GPL-3.0, making it freely available for personal and commercial use.
Links
For anyone already running a home server, Authman is a natural addition. It handles 2fa without requiring a paid subscription or an account with a third party.
