Running a Space Engineers server is all about giving players a stable, creative space to build, explore, and occasionally blow things up. But once your world is live, anyone can join unless you take steps to control access. That’s where adding a password becomes essential. It’s a simple change that protects your server from random players, griefers, or anyone who might disrupt the experience you’re trying to create. This guide walks you through the process of adding a password to your Space Engineers server, whether you’re hosting it locally, using the in‑game interface, or managing a dedicated server. You’ll learn where the setting lives, how to update it safely, and what to consider when choosing a password that keeps your world secure without making access a hassle for your friends or community.
