How to become admin on your Arma 3 server and use admin commands

Arma 3Updated Oct 5, 20263 min read
  1. Stop the server, open server.cfg in Files, and remove the // in front of the passwordAdmin line. Set it to your own admin password inside the quotes. If there is no passwordAdmin line in the file, add this line yourself: passwordAdmin = "yourpassword"; with your own password.
  2. Optional: to let trusted players log in without a password, remove the // in front of the admins[] line and list their player UIDs (their Steam ID 64 number) inside the braces, separated by commas.
  3. Start the server and join it from the game.
  4. In game, open chat (the / key by default), type #login followed by your admin password, and press Enter. If you are listed in admins[], type just #login.
  5. Once logged in, type #missions to choose a mission. Type #logout when you are done.
  6. Only one logged-in admin can be active at a time, and a new admin cannot log in until the current one logs out.
