To sum it up as best as possible, the log-in page is here to stay for the time being. Reasoning is that it's safer with the page rather than without it.
There has been some speculation about whether or not we will be permanently keeping the log-in page, and so far, it looks like it's here to stay. It's understandable that it can be tiresome and frustrating to keep the page open, but if you are not happy with the new security option, there are plenty of other games out there that won't hassle you with this function. We want everyone to be able to log in successfully and play the game, but if you are experiencing issues keeping the game open and refreshing the page, I would highly recommend taking a look over at the Help Boards-- there is usually always at least one user who is willing to lend a hand.
As it has already been explained before, the log-in page won't be going away anytime soon. It's simply too early to say whether we will be able to install other options, but this is the most reliable option that we have at the moment. The log-in page doesn't have to be your enemy-- it's there for your protection and our main priority is keeping folks safe.
