Ion Auth - Lightweight Auth System based on Redux Auth 2

Hi Ben,

Have a noob question. Just need a suggestion if Ion Auth would be suitable for my requirement. My site should have three types of users. A user, seller and the admin. So is it suitable for me to use Ion Auth or is it only suitable for one type of user and an admin. Do I need to make a lot of change if I use Ion Auth?

Thanks.
