How To Lock and unlock yourcomputer with a USB drive, Like AHacker

If you prevent access to your computer
with just a password, you are missing
out on an alternate (and more secure)
way to lock down your computer.
Predator, a free Windows program,
turns your USB drive into a key that
locks your computer when it’s removed.
To unlock your computer, you’ll have to
plug the USB drive back in. (Talk about
having secret-agent-style security.)
Anyone who attempts to access your
computer without the USB flash drive
will be hit with an epic “Access Denied”
message. To get started, follow this
Step 1: Download and install Predator.
Step 2: Once Predator launches, plug in
your USB flash drive. None of the
contents of the drive will be deleted or
altered in any way, so feel free to use
your primary thumbdrive.
When you insert the drive, a dialog box
will appear asking you to create a
password. Click OK to continue.
Step 3: In the Preferences window, take
note of a few key settings. First, enter a
secure, unique password in the “New

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 thumb drive 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.
Every 30 seconds, Predator will check to
see that your USB drive is plugged in. If
it isn’t, your computer will dim and lock
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. You can see the log at any time
by clicking “View log” from the
taskbar menu.
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. But
if you’re sold on Predator, consider
purchasing a USB hub to compensate.

thumbdrives you have lying around.
