I have often wondered if it would be possible to edit the Windows Vista login screen to have multiple layers of security such as instead of just entering your password you would have to;

*Enter password & USB Key

*Enter password & Fingerprint recognition

*Enter password, Fingerprint recognition & USB Key

I know this is not very necessary as Windows Vista login is already secure but it's just something I have always wondered about.

Thankyou for any help in advance.
