  • I hear that biometric products, if used with a backup password, are now called a “below-one factor authentication”, since it makes the users less safe than a password-only single factor authentication. It is exactly like a house with two entrances is less safe against burglars than a house with one entrance. This means that biometric products must be used without a backup password if security is wanted. Can it be done? It should help a lot if you have a quick look at http://www.slideshare.net/HitoshiKokumai/blind-spot-in-our-mind-eyecatching-experience
