Intel is working on it, teaming up with Symantec and Vasco on what's being broadly termed Identity Protection Technology, or IPT. This tech enables a computer to, in hardware, generate a one-time password (OTP) that a compatible site could accept. That computer would have been earlier paired with the site to ensure that only authorized machines sign on. It's similar to the random generating key fobs you might need to sign on to VPN, but built in to Intel's Core i3, i5, and i7 processors. Of course, that won't help if you e-mail your credit card number to a supposed friend who's supposedly stranded in some supposedly far away land, but it's progress.
