Two-factor authentication is coming to U.S. banks:Federal regulators will require banks to strengthen security for Internet customers through authentication that goes beyond mere user names and passwords, which have become too easy for criminals to exploit.

This won't help. It'll change the tactics of the criminals, but won't make them go away.
