Email addy also on login

[Max Taxable]

I've thought about this idea for a couple of days, and searched but didn't find anything close, but:

What if we had not only username and password required for login, but the email address as well? Like this:

Username ___________
Password ____________
Email Address _____________

Seems to me this would be the forever end of brute force password cracking. End of success for it anyway. It also adds the extra security of what basically is a second password, stumping the script kiddies and ending their efforts as well. They would just leave and go on to easier targets.

However I do realize this has some cons to it. Possible pain in the arse for the users, and also can browsers "remember" the email address field? Would this cause problems?

I haven't seen, ever, where any site has done this. Thoughts?
