Use USB drive to lock and unlock computer

If you want to control the access to your computer beyond just a password then one you can use very own USB drive to do that! Like a secret service agent :)  Meaning you hang your USB or a SMALL MICRO USB card in a key chain which would control the access of your laptop or desktop!

Step 1: Download and install Predator.

Step 3: In the Preferences window, enter a secure, unique password in the "New password" field. If you lose your USB drive, you'll use it to unlock your computer. So dont worry about lossing ur USB

If you'd like, you can check the Always Required box and you'll be asked to enter the password each time you use your thumbdrive to unlock your PC.

Finally, in the section under Flash Drives, ensure that the correct USB flash drive is selected. When you're done, click "Create key" and then OK.

Step 4: Predator will exit. When it does, click the Predator icon in the taskbar to restart the program. A few seconds later, the icon will turn green, alerting you that Predator is running.

Here are some extra tips:

To pause Predator at any time select "Pause monitoring" from the taskbar menu.

If someone tried to access your PC while it was locked down, you'll see the activity log when you log back in.

Predator's Web site has several cool how-tos, including one that shows you how to program your computer to take a snapshot each time someone tries and fails to log in to your computer. Check it out.

One obvious flaw comes with this setup: you'll always be down one USB port.
