You can setup Blizzard on your TOTP app as long as it supports 8 digit codes and you use this process.
I’m a gamer and I play way too much Call of Duty. I buy new games and don’t play them because I keep playing Call of Duty. I buy most of the expansion packs for each game, so they are making a decent amount of money from me, like the rest of you. It is a great game, but it has major flaws which I’m pretty sick of.
This post is mainly about Black Ops 2 because it is simply the most recent one that I’m playing. Most of these things apply to the previous Call of Duty games of which I’ve owned 2 or 3.
