You can do many things with computers. Some of them are more productive than others. My recent blog post shows how to authenticate to any service, such as Grafana. Some people took the idea of using Tailscale for authenticating to any service as a neat fact. Others took this as a challenge to come up with even more creative applications of Tailscale for authentication. This is the story of one of the latter cases. This is how you can make your Minecraft server join your tailnet and authenticate to it with Tailscale.
