One way to secure access to your PC is to purchase a special K3Y key. It’s a flash drive that works as a physical key to unlock your device. If it’s plugged in and the correct password is entered, the device is unlocked. Remove the flash drive — and it locks again.

With the free [**USB Raptor**](https://sourceforge.net/projects/usbraptor/) utility, you can avoid buying such a key. Instead, you can turn any flash drive into a K3Y key.

You don’t need to do anything complicated: just plug in the flash drive and launch the utility. In the utility, specify the access password, click **Create k3y file**, and enable the **Enable USB Raptor** checkbox.

That’s all for the basic setup. Now when you start your PC, it will require you to plug in the flash drive and enter the password.
