Humble bundle can't log in

No problem for me. I was already logged in to it, but I just tried doing it in a new incognito window and had no trouble. I'm on Chrome, and I logged in via Google account, if that helps.

yep same here I tried logging in with my Google account, but it won't let me.
I was previously logged in but couldn’t reveal the key. When I tried to log in again, it redirect me to login screen

thanks for the replies. Good to know it wasn't only me. It works now
