How to Add Admins on Your Arma Reforger Server

Set up admin access on your Arma Reforger server using the admin password and Steam ID whitelist for passwordless login.

Arma Reforger has two ways to grant admin access:

You can use either, or both together.

Set the Admin Password

In the XGamingServer Panel, click Arma Reforger Config in the sidebar (or click Open Config Editor on the dashboard banner).

Config Tool in the sidebar

Click the Game tab in the editor.

Config Editor Game tab

Enter a value in the Admin Password field. Alphanumeric only, no spaces.

Click Save Changes, then restart the server from Console.

Go to Console in the panel and stop the server.

Click Files in the sidebar and open config.json.

"game": {
  "passwordAdmin": "YourAdminPassword"
}

Click Save Content and start from Console.

Press C in the lobby or Enter in-game to open chat.

Type:

#login YourAdminPassword

Press Enter.

Once authenticated, you can access Game Master mode from the pause menu and use admin commands.

Players in this list can type just #login (without a password) to become admin. Maximum 20 entries.

In Arma Reforger Config, go to the Game tab.

In the Admin Steam/Identity IDs field, enter one SteamID64 per line. Find IDs at steamid.io.

76561198012345678
76561198087654321

Click Save Changes and restart.

In config.json, add the admins array:

"admins": [
  "76561198012345678",
  "76561198087654321"
]

Save and restart.

Problem	Fix
`#login` doesn't work	Make sure the admin password is alphanumeric only — no spaces or symbols
Steam ID whitelist not working	Verify the IDs are SteamID64 format (17 digits starting with 7656). Check there are no extra spaces
Lost admin after rejoining	Admin status persists for the session only — re-run `#login` after rejoining
Can't access Game Master	Make sure you're authenticated as admin first, then look for the option in the pause menu
