I typically keep myself logged in, so I had to log out to see what you mean.
it looks like they are trying to expand way for people to play by adding other options for logging in besides the credentials you originally use. It took me a few tries to figure out how to login now.
For me it is the very top option on the screen and it doesn’t allow me to put in my name and my password at the same time but forces me into screen screen. It is a bit irritating. I can’t imagine why it was reprogrammed, but that is how it is on BGA. Who knows what goes on in the background for these decisions ?
