Passwords vs. biometrics (GCN)

The password by itself actually is a pretty good tool. It is simple to use, easy to implement and can be reasonably strong. The problem is one of scale. For a user juggling passwords for multiple accounts and for administrators juggling many users, the system quickly becomes unwieldy, and strong security begins to break down.
