Just an FYI, I could not find a Log In prompt this morning. There was a prompt to create an account (and log in) on the far left of the screen. But the log in part didn't show until my cursor moved over it. I then had to start the new account process and then there is an agreement clause you need to accept. After I did that I was provided a log in prompt and was able to do so.
So, getting logged in takes a bit of detective work, but is doable.
