If you didn’t know what a “Dongle” is, a dongle is a small hardware device that connects to a computer to authenticate a piece of software. When the dongle is not present, the software runs in a restricted mode or refuses to run. Same with this case, you can use your USB flash drive and make it like a Dongle. To login to your user account, simply plug in your USB flash drive and it will allow you to login. If other unauthorized USB flash drive is plugged in, it’ll automatically logoff. A good way to secure your Windows log in if you’re a person who can’t remember anything including passwords!


Blue Micro USB Flash Drive is design for personal use with simple security features for the computer systems. The software creates a encryption data to the USB flash drive and the user has to logon to the computer using the configured USB flash drive. Therefore the USB flash drive acts like a key for the computer. Users do not need to remember password and encryption is not dependent on windows system itself. The encrypted data is completely proprietary information. This software can be installed on windows XP or 2000 only.

I tried it and it works. I also tried to boot in to Safe Mode and see if it will bypass this security but it also ask for the USB key to login. I believe it’s much safer to use this method to protect your computer from illegal logins compared to the Windows login. This is because there are already so many ways to crack Windows account password(do a search here and you’ll find a few articles on how to crack and hack into Windows). A hacker/cracker can crack all the passwords he wants, but without the USB flash drive, he can’t get in to that user account that he wants to.

The author of Blue Micro USB Flash Drive did say “If you are facing any serious problem after installing this application, you can reinstall windows xp or 2000 without formatting your computer. This process will reinstall windows xp or 2000 by restoring your computer settings back to normal without effecting windows configurations.” Seems like there is no way to hack in, unless you reinstall Windows which takes time.

Very easy to install and use. Just download, install and run it. First of all, you need to create the encrypted data to login. Enter a 14 digit access code, then the drive letter of your USB flash drive and finally click the “Create My Flash Drive Key” button. You will get a notification saying “Your flash drive key has been created. Please enable your flash drive logon in the Enable/Disable Logon tab”.

Next, you need to enable user logon and also flash drive logon application. Just click on the Enable/Disable Logon tab, and then click on the “Disable” button to Enable it.

You must also be very careful not to delete the file “bmpl.txt” in your USB root. That’s the file that contains the encrypted data which is recognized by Blue Micro USB Flash Drive. If someone copies that files to another USB flash drive, he too can login to your computer using HIS USB flash drive. Another way to recreate the bmpl.txt file is if you remember the 14 digit access code. You have to install Blue Micro USB Flash Drive Logon software on another computer, and then recreate the bmpl.txt file from there.
