I noticed Twitter did something similar the other day. I was trying to login from my phone, and after two failed login attempts, I got an email with a confirmation code that I could enter into the Twitter app (on my android phone) to login. The email said I could also use this "code" in place of my password. > We noticed that someone recently tried to sign in to your Twitter account (...) > If this was you, confirm your identity by using this temporary code: (....) > You can also enter this code where you would normally enter your password when you sign in. I couldn't tell whether the email was sent because the second password attempt was successful or because it wasn't successful.
