Do you feel like you're fighting a losing battle against your ever-expanding list of Web site usernames and passwords? Are you tired of Web sites asking for your mother's maiden name or your pet's birthday in order to be e-mailed your account information? The good news is that more and more devices are building in biometric security--a feature that identifies a person by a unique physical characteristic, most often a fingerprint. Most biometric sensors read the electrical characteristics of a fingerprint, making them equally easy to use and hard to fool. (OK, we know what you're thinking: If someone cuts off my finger, will he or she be able to log in to my e-mail? Fortunately, a severed finger will work on most sensors for only a few minutes, after which its electrical properties degrade, which is good to know.) We've rounded up laptops, keyboards, and PDAs that have biometric security. So, instead of always having to hunt for your passwords, with these devices, you'll have them at your fingertip.
