2004: Microsoft Fingerprint Reader
Using different passwords can be a pain to remember and using the same one for all your accounts is a risky practice. So in 2004, Microsoft introduced a fingerprint scanner to help alleviate password headaches... but probably ended up inducing more trouble of a different kind.
The device could store up to 10 fingerprints per user, each of which would be registered with a username and password and stored on your system. It was marketed as a tool of convenience and not security because the system didn't encrypt the saved fingerprint data. Indeed, anyone with the right tools could gain access to the fingerprint files, and thus all the information belonging to the owner of each digit.
