How to Set a Password on Your Space Engineers Server

Published June 9, 2026 · By Host Havoc Technical Support Team

To protect your Space Engineers server with a join password, you must generate a password hash and salt and add them to SpaceEngineers-Dedicated.cfg. Two methods are available.

Once a password is set, players will see a prompt when joining your server and must enter it to connect.

Method 1: Online Hash Generator

Generate your hash and salt

  1. Stop your server.
  2. Open https://sepg.einarjegorov.com/ in a browser.

  4. Note the generated hash and salt values.

Apply the values

  2. Locate the Server Password Hash and Server Password Salt fields and paste the generated values into the correct fields.
  3. Click Save & Exit and start your server.

  3. Select Local/Console and click Continue to server configuration.
  4. In the Password field, type your desired password and click Save.
  5. Click the Edit button next to Save. This opens a Notepad file with your configuration.
  6. Find these two lines (the values below are examples only):
