Google Aims To Eliminate Need For Passwords, Looks To Cryptography

Laugh until someone steals this little gizmo and digitally rapes you.

Exactly!!!!!! Keys work great for cars if you lose your keys it almost never means that you will be losing your car or its contents as well. I have a spare at the house, you can het a ride from a friend, taxi, bus, and it becomes a huge inconvenience to lose cars keys... Losing your cellphone or a secure key card like this and on could be SCREWED risking access to all your information, and what if you lose it while on a business trip and can't access files you need for work etc. Almost 10 years ago Paypal introduced a digital keyfob that generated a pass key every X hours for free so I ordered it tried it out and a week into it forgot th keyfob at home and had no way of accessing the addresses I needed to ship items. I deactivated the fob and went back to good ol' passwords.

Here's my solution: Instead of a stupid ****ing key that will *always* be in the laptop, do this:

A program that syncs between the laptop BIOS and your smardphone. When your phone is in range = good. When not in range and answering the crypto correctly... sleep mode. Then, if someone steals your computer, they get a brick with a password-protected BIOS and full-drive encrypted system.

Have the syncing process generate a 64-digit key that people can manually enter if their phone dies or is stolen. They can write this down and keep it in their fire-safe at home.

Good points, but the whole idea is that the "key" stays with you the user, not with your computer, be it a ring or an authenticated smartphone. The idea you propose is, as far as I can tell, exactly what Google is looking at doing with the ring--which, IMO, is a way better idea than using a smartphone. (Rings tend to stay on your fingers. Smartphones tend to get lost or stolen.)
