Two step

Hello,i use google authenticator for my two step,and i can't log inside the game with the code i get,i can log into site,but not inside the game,i triple checked my name and my password it's correct,but it won't log in with the number,for me it's easier to use google than mail for personal reasons,i just wonder why is this happening?

I figured it out,you have to use the code in you have once u go to security page,next to bar code,you have to type the code in authenthication bar below the password in game,and than you have to type the numbers you get on app,but this is strange it did not require you to do this in the past,why is it happening now?
