Arma Reforger servers offer several options to prevent random users from connecting. Server administrators can manage a server whitelist, which allows only specific users to join, or a server password, which allows any user who knows it to enter. By using a server password, private lobbies can be further enhanced with game masters and all players knowing each other.
1. Log in to the BisectHosting Starbase panel.
2. Stop the server.
3. Go to the Startup tab.
4. From the Server Password field, enter the desired password.
