The future of the password could be biometric

As far back as 2004, Bill Gates was predicting the demise of the password.
In 2012, his prognostication might actually come true.
Researchers are working on ways to either eliminate the headache of having to remember a gazillion passwords, or to at least make passwords more secure.
The fundamental flaw of passwords is that no matter how long or complicated you make them, they will always open your device to whoever figures out the exact code. But future methods of authentication will not open the door to anyone with the key. They will — hopefully, at least — open the door only to you.
Several of the avenues being explored trade on recognizing “biometric” features, such as hand gestures, typing quirks, voices and more. IBM’s 2012 forecast predicts that passwords will become obsolete: “Biometric data — facial definitions, retinal scans and voice files — will be composited through software to build your DNA unique online password,” the company’s SmarterPlanet blog (no relation!) said .
