  2. Stop your server if it is currently running.
  3. Click Configuration Files, then open the Text Editor for the server.cfg file.
  4. Locate the line //password = "ServerPassword"; and remove the two // characters at the beginning to uncomment it.
  5. Replace ServerPassword with your desired password.
  6. Click Save.
    The save button in the Arma 3 server.cfg text editor after setting the server password
  7. Start your server. Players will now be prompted to enter the password when connecting.

Note: To remove the password later, re-add the // characters at the start of the password line, save, and restart the server.
