Wtf is going on? I just downloaded and made an account and I can't even log in?

On my Gamer's First profile, I've been given a random string of numbers/letters as a username and some gigantic password that is not the password I typed in. And when I tried to edit the password, it told me I couldn't use the same password as my old one. Huh? But the length of the password displayed on my profile is obviously much longer than the password I typed in myself when I was initially giving my email. I can't copy and paste these random username and passwords into the launcher - and I'm not seeing anywhere where I can edit and change them to something I actually know. A quick google search of this problem suggested there might be maintenance going on - but looking at the website, the servers are currently online. Pretty frustrating.
