If it is a Mac then Origin. If it is a windows pc it will be the Ea app instead. You can save your ea folder from my documents on your old computer and replace it with the new one created on your new computer once you ran the game once. That way you wont lose all your goodies. I had to do that all when my computer got factory reset and will have to do it all again when I get a new laptop too, busy saving for one. Origin was no where as an option for me, so I had to take the scary step to install the ea app. It was all goods though ;)
