A loss prevention device, SecurLock is a USB key/software solution for Windows 2000 and XP. (Note: key in photo indicates scale and is not part of SecurLock system). When inserted into a USB port on your system, it performs user logon authentication, file encryption, and storage for all of your passwords and logon profiles. It can store this type of information for several users on the same system.
If the “key” is removed from the USB port, you will be prompted to insert it when you boot the computer. If you insert it before turning on the system, or did not remove it when you last shut down the computer, you’ll be prompted to type in the PIN you selected during setup. The computer can’t be accessed at all without the SecurLock USB key.

As well, SecurLock blocks access after three incorrect PIN attempts. At this point, only an administrator can unblock it. Of course, if you’ve installed SecurLock on a stand-alone system that only you use , you are the administrator.
Right-clicking also offers the option of locking a file for transfer on floppy disk or by email, or making it self-extracting. Simply right-click, select the encryption or lock you want, and choose a password. To read the file, the recipient must also know the password.
The Single Sign-On (SSO) feature allows you to store all your logon names and passwords in one encrypted location. Each identity is stored under an icon with individual names. When you go to a Web site that requires a login, simply drag and drop the appropriate icon onto the Web page and click to enter rather than typing in a name and password.
Unlike some USB keys, SecurLock is internally shielded to protect it from static electricity damage.
