Single Sign-On for Your Self-Hosted Stack

If you run your own services—a homelab, internal tools, or a suite of self-hosted apps—you know the pain of managing separate logins. One password for your analytics dashboard, another for your file server, and yet another for your monitoring tool. It’s messy, insecure, and frankly, a hassle. What if you could bring the simplicity of single sign-on (SSO) to your own hosted environment, without needing a complex enterprise identity provider?

Enter VoidAuth. It’s a lightweight, self-hosted SSO solution designed to bring unified authentication to your personal or internal services. Think of it as a simple gatekeeper that lets you sign in once and access all your connected apps.

What It Does

VoidAuth is an authentication server that acts as a central hub for logging into multiple services. Instead of each app handling its own users and passwords, they delegate authentication to VoidAuth. You log into VoidAuth once, and it securely passes your identity to any connected service that trusts it. It’s built to be simple to set up and integrate, especially with common web apps and services that support OAuth or similar protocols.

Why It’s Cool

The clever part is the balance it strikes. VoidAuth isn’t trying to be the next giant enterprise identity platform. It’s purpose-built for developers and tinkerers who host their own software. It’s likely lightweight, meaning you can run it on a small VM or even a Raspberry Pi alongside your other services. The implementation probably focuses on standards like OAuth 2.0 or OpenID Connect, making it easier to integrate with a wide range of software that already supports those protocols.

The use case is perfect for anyone with a growing self-hosted ecosystem. Got Nextcloud, Grafana, and a custom admin panel? Instead of managing three user lists, you manage one. It centralizes security, simplifies user management (adding or removing someone happens in one place), and improves the user experience for anyone accessing your services.

How to Try It

The project is hosted on GitHub, so you can jump right in. Head over to the VoidAuth repository to check out the source code, documentation, and setup instructions. Since it’s a self-hosted tool, you’ll typically clone the repo, configure it with your environment details (like a secret key and allowed redirect URLs), and run it—likely via Docker or directly with Node.js/Python depending on its stack. The README should guide you through deploying it and connecting your first application.

Final Thoughts

For developers running a personal lab or a small set of internal tools, VoidAuth looks like a solid step toward a more professional and manageable setup. It tackles a real, everyday annoyance with a focused solution. It won’t replace Auth0 for a massive SaaS product, but it doesn’t need to. Its job is to make your life simpler and your self-hosted stack more cohesive. If you’re tired of password sprawl across your own services, this is definitely worth a weekend experiment.
