To set a password on a FREAKHOSTING Arma 3 server, open Startup, type it in Server Password and restart the server. The panel writes it to the password line of server.cfg at every start, so set it on Startup, not in the file. Leave the field empty for a public server. Players enter the password when they join.

​
How to set or change the server password

1

Open Startup

Open your server in the Game Panel and click Startup.
2

Enter the password

Type the password in Server Password. Click outside the field to save it.
3

Restart the server

Restart. The new password applies from the next start.
4

Join with the password

In the Arma 3 Launcher or the server browser, join the server and enter the password when asked.
To remove the password, clear Server Password and restart.

​
How to change the number of player slots

Max Players on the same page sets maxPlayers in server.cfg at every start. The default is 32. The real limit is the lower of this number and the number of playable slots in the mission.

​
Three different Arma 3 passwords

Use a different value for each. Anyone with the admin password can kick, ban and change missions.

​
Fixes when the password doesn’t work

  1. Restart after a change. The server reads the password only when it starts.
  2. Don’t edit the password in server.cfg. The panel replaces it with the Server Password value at the next start.
  3. Type it exactly. Retype it instead of pasting, so no space is copied, and match capital letters.
  4. Check the server. Compare the address you join with the address on the Console page.

​
Frequently asked questions

​
Can I hide my Arma 3 server from the server list?

A password keeps strangers out, but the server still shows in the list. Players without the password can’t join.

​
Do headless clients need the password?

No extra step. Headless clients started by the panel use the Server Password automatically. See headless clients.

​
Where can I see the current server password?

On Startup in Server Password. The password line in server.cfg shows the same value after the server has started.
