How to Set a Password on Your Space Engineers Server

You can protect your server with a password so that only players who know it can join. Space Engineers does not store the password in plain text but as a hash and salt value in the server config. You generate these two values once and enter them into the config.

Generate the hash and salt

Use the official Space Engineers Dedicated Server tool (free in your Steam library under Tools):

1. Install the tool
   Install and start the "Space Engineers Dedicated Server" tool via Steam.

2. Enter the password
   Enter your desired password in the Password field. The tool automatically generates the ServerPasswordHash and ServerPasswordSalt values in its own SpaceEngineers-Dedicated.cfg.

3. Copy the values
   Open the SpaceEngineers-Dedicated.cfg generated by the tool and copy the contents of <ServerPasswordHash> and <ServerPasswordSalt>.

Transfer the values to the server

1. Stop the server
   Stop your server via the dashboard.

2. Connect via SFTP
   Connect to your server via SFTP, or use the file browser.

3. Open the config
   Open the file /config/SpaceEngineers-Dedicated.cfg.

4. Enter the values
   Enter the copied values:

   <ServerPasswordHash>YourHashValue</ServerPasswordHash>
   <ServerPasswordSalt>YourSaltValue</ServerPasswordSalt>
   

5. Start the server
   Save the file and start your server. Players are prompted for the password when they connect.
