i'm not sure if you mean by georgraphic location or what, but if that's what you mean, then in this case yes, just do not give your account details to anyone else, it is your account alone
You have to know the IP of the server (ex 71.243.5.191)...go to MySQL Database > Access Hosts > Add the IP, like I would add 71.243.5.194...and if I had apache/php or whatever on my PC then i could connect to 72.232.204.42 with the username of network_whatever and password of whatever and database of network_whateevr. Change whatever to your info and network to your cPanel username.
