ScoularjThe GateKeeper isn't meant to guard against bypassing the password. If the USB is unplugged, the computer will lock and require the normal Windows password to login. The GateKeeper is meant to make certain aspects of computer access more convenient and secure - it is not an all-in-one security system. Many of our clients use the GateKeeper to lock unattended terminals, access multiple machines that may even ahve different passwords (less passwords to remember), and to stay logged in (eg police driving and healthcare professionals at a patient terminal).
