If you've got a security token on your account it overrides the IP check so you'd be able to login from anywhere without any issues.

Also I don't know if this helps, but you can actually copy and run the game on a USB drive (I've done this myself a few times). So if you were to do that you'd only to have a few minutes access to any computer running Windows. Because configuration files/hotbars are stored on your local computer you wouldn't have any of those without getting creative, but for logging in and walking inside your house, it's not like you'd need those.
