If it is possible open 2 accounts (and window game) at the same time?
You need one key each for each game you want to bot on. Other than that you can open more than 2 on the same PC. I am running 4 on one pc
FFXIV has a limit in place that only lets you open 2 accounts. The bot however removes this limit and allows you to open as many accounts as your computer can handle.
