I'm using Blizzard Authenticator and Starcraft II login screen prompts me each time to enter the code. Everything would appear to be fine, unfortunately it isn't:
Blizzard recently announced that they have updated the authentication system to intelligently track login locations and, if one is consistently connecting from the same place, may not be asked for an authenticator code.
That new feature worked flawlessly for a few days, but suddenly it stopped. Nothing changed in my machine, and I'm using the very same computer to play. I'm being prompted again to enter the code every time, even after watching a legacy replay.
I want to find out what's causing the problem. I would really appreciate any advice you may have.
UPDATE: I have a static IP (Sorry I didn't mention that sooner)
