You exceeded the maximum allowed number of login attempts. In addition to your username and password you now also have to enter the confirm code from the image you see below.
I only tried to log in once and as soon as I hit "Login" that popped up. So I'm not sure if it's a glitch or ...................... what.

Just wanted to put the FYI out there that it happened on my first time logging in this morning. No biggie really though.
