If you attended the connected health conference last week, you got a USB key with a combination lock on it, so you could protect your important data against those with less than 10 minutes of free time, or those with very little imagination.

But to get this protection, you'll need to change the combination to some other number. Here's how you do it:

1. Set the key to 0-0-0
2. On the non-usb end, there's a small round button. Press it in with a pen.
3. Change the combination
4. Press the button on the USB end back in.
