Biometric technologies can supplement or even replace passwords entirely when used in conjunction with a password management program. The following biometrics vendors can turn almost any physical aspect of your body into an authentication mechanism. The EyeVerify app looks at the blood vessels in your eyes to confirm your identity, and the EyeLock Myris collects 240 points of data on your iris. The Onyx, from Diamond Fortress Technologies, uses the camera on your smartphone, and free demo apps are available for both Android and iOS.”]
