How to Change Your Factorio Server Name and Password

Updated June 10, 2026 · By Host Havoc Technical Support Team

Your Factorio server's name and password are controlled by server-settings.json. Editing this file through the game panel applies the changes at next startup without any manual file transfers.

For file-based changes such as uploading mods or saves, see Connect an FTP Client.

Change the server name and password

  1. Log in to the Game Control Panel and navigate to your server.
  2. Stop your server.
  3. Click Configuration Files.
  4. Locate server-settings.json and click Config Editor.
  5. Edit the name field to set your server name and the password field to set a join password. Leave password empty for a public server.
  6. Click Save.
  7. Start your server. The new name and password take effect immediately.

Troubleshooting

  • Server still shows old name: Confirm the server was fully stopped before saving. Restart once more after saving.
  • Config Editor not saving: Check that no field exceeds its allowed length. Switch to the Text Editor view to inspect the raw JSON if needed.
  • Password not working for players: The password field in server-settings.json is case-sensitive. Share it exactly as entered.
