go to your file manager in the game panel then to mods>deathmatch then open the mtaserver.conf. Now on line 117 you will find ' <!-- If set, players will have to provide a password specified below, before they can connect to the
server. If left blank, server doesn't require a password from them. -->
<password></password>'
type in your password between the <password></password>.
restart your server and you are set up!
