Well, this is new. I guess this is for further authentication.

I'm not entirely sure but, I think in-game, you will input the certain information they'll be looking for. That is, the date when you received the authentication code (format: 2015年MM月DD日) and the authentication code (that 8-digit code you first saw).

Btw. I suggest deleting that imgur album asap.
