I have 2-factor authentication enabled (in fact, it's part of my company's security policy that everyone must follow).. but I went to that page and saw shitloads of "user.failed_login" messages over the past five days and it kind of freaks me out.

That said, it kind of freaks me out in a good way. I'm glad github has this panel. People should be aware when several failed login attempts are made on their accounts.
