Step-by-Step Usage

Download USB Raptor from the official SourceForge page:

Extract the downloaded Zip File & Install the application following the on-screen instructions.

After installation, launch USB Raptor on your computer.

To Configure USB Key, Insert the USB key that you want to use for authentication. In USB Raptor, we can see Simple Configuration options as well. But let’s use Simple Configuration. You can surf advance options too.

Click on Create k3y file button to proceed.

Mmmmm… It was processed within 0 sec. Let’s enable & test it. Click on enable. (Remember that you can’t change the password while the USB Raptor is enabled)

Yay! It works. HAHA!! TBH for a sec it felt like a big treasure is hidden on my computer lmao. But it was great.

On surfing more advances configuration options I came across several interesting features like it also offers an automated USB lock and unlock function, with encrypted lock file contents for added security. I was able to enable a password override and even employ network commands for unlocking. Also, USB drive serial number checks, unique keys for each system, and a status report function enhance customization feature was great.

Further, I tried this using multiple USB drives to ensure compatibility with all types of USB flash drives n it also supported automated Windows lock/unlock through common drives on my computer. As per more tests I can conclude that the program is robust, easy to set up, and provides a high-security option to us by verifying flash drive serial numbers which is the feature I personally liked about it. It also supports various alternative unlock methods, LAN lockdown and unlock functions, multi-screen system support, and compatibility with Windows 10, 7, 8, and XP as well...

I also tried synchronized lock/unlock on LAN for multiple PCs at my workplace, it also provided the status reports over the internet and LAN, serial command integration (beta stage), tray icon-based application, delay and cancel options to avoid unwanted locks, log files, and master key support. One more best feature I liked is that we can also select backdoor access options, and each key can be unique for individual systems.
