How To Use A Whitelist On Your Open World RimWorld Server

A whitelist lets only the players you choose join your Open World server. Add your players first, then turn the whitelist on.

Adding Players to the Whitelist

  1. 1
    Log in to Bropanel and Stop your server.
  2. 2
    In the sidebar, go to Files.
  3. 3
    Open Data/Whitelist.json.
  4. 4
    Replace the example names under WhitelistedUsernames with your players' usernames, each in quotes and separated by commas, for example ["PlayerOne", "PlayerTwo"]. Then save the file.
  5. 5
    Start your server.

Usernames must match exactly, including capital letters. To add players later without a restart, edit the file, then type reload in the Console and press Enter.

Turning On the Whitelist

  1. 1
    Log in to Bropanel and select your server.
  2. 2
    In the sidebar, go to Settings.
  3. 3
    Under Basic, enable Use Whitelist.
