I have been trying to use Google Authenticator (GA) but the QR code does not work. It is not a big deal as manually keying in the code into GA works too; however this is not mentioned anywhere in the setup instructions (yes, spoonfeeding is expected here as IT things have a way of going south when instructions are sometimes not strictly followed).
My main issue is after a few days, the GW2 profile in my GA on my iPhone self resets, wiping out the profile I have setup for GW2. I have already had to manually unlink the 2 factor authentication process a few times.
I would love to use the GW2’s 2FA but not when the app resets itself whenever it feels like it. I have reinstalled the app a number of times and being an iPhone user, there is a VERY short list of things I can try to troubleshoot the problem (is it the app, the phone or something else?).
