Are biometrics more secure than passwords?
The security of a password depends on the user. If the user has to memorize too many passwords, he will use the same passwords for as many applications as possible. If this is not possible, he will go to construct very simple passwords. He might even write the password down on paper. This would transform “secret knowledge” into “personal possession”. Of course, not every user will react this way. Rather the personal motivation plays an important role: is he aware of the potential loss caused by careless handling of the password? It is easy if the user is the owner. But often foreign possession (e.g., that of the employer) has to be guarded, whose value one often can hardly estimate. If motivation is missing, any password primarily tends to be felt bothersome. In this case, and that seems to be the normal case, it is assumed that biometrics has considerable advantages. in their favour, passwords feature an unbeatable theoretic protection ability: an eight-digit password which is allowed
