Home labs may be the perfect testing grounds for your virtualization projects and computing experiments, but they can also double as rock-solid self-hosting workstations once you arm them with the right containers and VMs. However, remembering the credentials for each service can become a problem once you’ve deployed dozens of containers for your productivity, media consumption, and storage needs.

Hosting a Single Sign-On authentication server can alleviate your username and password management woes. As you may have guessed from the name, an SSO server lets you sign in to your entire application stack without forcing you to recall the credentials for every service. Authentik is one of my favorite services for SSO logins, and here are four reasons why I recommend it to every home labber.

4 Easy to deploy

It even generates a self-signed certificate

Creating a self-signed certificate is undoubtedly useful when you want to secure your home server. But even with the killer Caddy + Let’s Encrypt combo, creating one can be really cumbersome when you’re just starting out – which is something I learned the hard way when I tried to deploy Authelia right after assembling my home server.

Thankfully, Authentik is one of the simplest SSO utilities for newcomers. Not only can you whip out an Authentik container within a couple of minutes, but you also don’t have to worry about tinkering with reverse proxies or certificates. That’s because Authentik automatically generates a self-signed certificate that’s valid for a year when you deploy its container, making it the perfect starting point for folks new to the arcane art of SSO.

3 Intuitive web UI

That doesn’t require constant YAML tweaks

Tinkering with YAML files and executing terminal commands is the way to go for DevOps enthusiasts and hardcore computing maestros. However, it’s hard to deny the convenience of a menu-driven web interface that lets you toggle a bunch of settings instead of forcing you to dabble in arguments and variables inside config files.

Authentik has a robust UI that’s easy enough for beginners and laden with all the features you could ask for as a self-hosting veteran. Unlike Authelia, Authentik lets you control everything from app configurations and protocols to users, flow-based automation, and tokens via the web UI. And that’s before we dive into the rest of its features…

2 Solid logging provisions

Logs for your login attempts

While there are plenty of precautions you can take for your SSO-powered home server, even the most secure system has certain loopholes that can be exploited. Thankfully, Authentik creates logs every time a user tries to log into your self-hosted stack, and you can even get a detailed overview of all the events that occurred during a failed sign-in request.

As if that’s not enough, Authentik also lets you create custom notification rules, where you can configure trigger-action commands for different events. And these events aren’t limited to failed login attempts either; Authentik can notify you whenever it detects flow/policy executions, suspicious requests, and config errors.

1 Support for multiple protocols

Alongside several policies and custom branding options

OAuth may be one of the most popular authorization protocols, but there are plenty of other standards you might want to leverage in your home lab. Perhaps you’re an Azure developer who uses SCIM for identity management. Or maybe you’re a DevOps/sysadmin expert who relies on RADIUS for network-level authorization.

Authentik is compatible with a barrage of authentication and authorization protocols, including OAuth2, SAML2, LDAP, RADIUS, and SCIM, making it more useful than Keycloak and other SSO alternatives. Heck, you can even configure an RAC provider inside Authentik and easily access your virtual machines and home lab over the SSH, RDP, and VNC protocols. Throw in the password policies and branding support for your self-hosted services, and Authentik becomes a top-notch addition to your home lab suite.

Make signing in to your home lab a breeze with Authentik

If you face the dilemma of setting weak yet easy-to-remember passwords and complex Eldritch credentials as often as I do, an Authentik container is hands-down the best solution. That said, this article wouldn’t be complete if I didn’t go over the biggest weakness of an Authentik server: its extra resource consumption.

Unlike Authelia, Authentik requires at least 2 cores and 2GB of memory. For a server-grade home lab with dozens of CPU cores and multiple high-capacity RAM sticks, Authentik’s system requirements won’t be a big deal – and I recommend this neat utility over other self-hosted SSO services. But for folks with low-end mini-PCs, budget-friendly NAS, or outdated PCs with a limited number of resources for their application stack, Authelia or Keycloak might be the better alternatives.
