How to Log In as Admin on Your Arma 3 Server

Updated 10 June 2026 · By Host Havoc Technical Support Team

Logging in as an administrator on your Arma 3 server lets you run server commands, kick players, and manage missions in real time. Your admin password is stored in the server.cfg file. You may also want to add a server password to restrict who can join, or review difficulty settings to configure gameplay options.

Steps

  1. Log into your Game Control Panel.
  2. Click Configuration Files, then open the Text Editor for the server.cfg file.
  3. Locate the passwordAdmin = line and take note of the password value.
  4. Launch Arma 3 and connect to your server.
  5. Press the / key on your keyboard to open the chat box.
  6. Type #login yourpasswordhere (replacing yourpasswordhere with your actual admin password) and press Enter.

You are now logged in as an administrator. For a full list of admin commands available in Arma 3, see the official Multiplayer Server Commands reference.

Tip: If you have not set a custom admin password, check the default value in server.cfg. It is recommended to change it to a unique password before making your server public.
