What airline is it and is it a domestic flight? It's usually 2 hours for abroad and 1 hour for domestic. The info should be on your e-ticket and their website.
If you get your bording pass later today, then you are already checked in. All you will have to do is drop your bag off if you have one, or just proceed straight to Security. Even 2 hours is giving you more than enough time but I always aim to be early just in case there are traffic problems etc.
