How To Password Protect Your USB Stick/External HDD in 3 Easy Ways

USB thumb drives/ external HDD are small, portable, and can be read on any device with a USB port. These features make them the perfect vehicles to transport data between computers. Due to their portability, however, they are also easily lost. Thus sensitive files callired on a USB stick should always be protected.

Unfortunately, you cannot simply password protect your entire USB stick, like you have password protected your Facebook account. Tools that will seriously protect your your data, all work with encryption. Unless you want to invest in a secure flash drive with hardware encryption, you can use freeware applications to achieve a similar level of protection. This article summarizes some of the easiest ways to password protect files and folders on your computer.

1. Manually Save Files With a Password

As mentioned above, you can’t safely password protect your entire USB stick without using encryption. However, if you shy away from the time consuming encryption process of entire folders and need a really quick way to only protect a few selected files, maybe you can simply save those with a USB password.

Many programs, including Word and Excel, allow you to save files with a password. For example in Word, while the document is open, go to > Tools > Options and switch to the Security tab. Now enter a Password to open, click OK, re-enter the password when asked, and finally save your document and don’t forget the password.




2. Create An Encrypted & Password Protected Partition With Rohos Mini Drive

Many tools can encrypt and password protect your data. Most, however, require Administrator rights to run on any given computer. Unfortunately, this is also the case for one of the best encryption tools: TrueCrypt. Tools like these are not a viable solution if you need to securely transfer data to a computer where you do not have Administrator rights.

Rohos Mini Drive, on the other hand, is a tool that will work whether or not you possess Administrator rights. The free edition can create a hidden, encrypted, and password protected partition of up to 2GB on your USB flash drive. The tool uses automatic on-the-fly encryption with AES 256 bit key length. Thanks to the portable Rohos Disk Browser, which is installed directly on your flash drive, no encryption drivers need to be available on the local system. Subsequently the protected data will be accessible anywhere.





Once you have created a password protected and encrypted container on your external drive, you can open it by clicking the Rohos Mini.exe icon from the root folder. After entering the password, your Rohos disk will be mounted and accessible via your Computer, i.e. the directory of all drives and partitions connected to your system. To close your Rohos partition, right-click the Rohos icon in the Windows taskbar notification area and select Disconnect.

3. Lock Your Flash Drive with USB Safeguard

Like Rohos Mini Drive, USB Safeguard is a portable app that runs directly from your flash drive and thus does not require Administrator rights on the local computer. It uses on-the-fly AES 256 bit encryption. The free version is limited to drive size of 2GB.

Download the usbsafeguard.exe and copy it to your USB flash drive. Run it from your flash drive and enter a password to lock the drive. To unlock it, run the file again and enter the password. The locking procedure must be repeated every time you want the drive to be locked as the tool will remember its last status, i.e. locked or unlocked. This also means that you can change the password every time you use USB Safeguard.

How to Crack the Account Password on Any Operating System

Computer passwords are like locks on doors – they keep honest people honest. If someone wishes to gain access to your laptop or computer, a simple login password will not stop them. Most computer users do not realize how simple it is to access the login password for a computer, and end up leaving vulnerable data on their computer, unencrypted and easy to access.

Are you curious how easy it is for someone to gain access to your computer? If so, read on to see the technique one might use to figure out your computer password.

Windows 
Windows is still the most popular operating system, and the method used to discover the login password is 
the easiest. The program used is called Ophcrack, and it is free. Ophcrack is based on Slackware, and uses rainbow tables to solve passwords up to 14 characters in length. The time required to solve a password? Generally 10 seconds. The expertise needed? None.
Simply download the Ophcrack ISO and burn it to a CD (or load it onto a USB drive via UNetbootin). Insert the CD into a machine you would like to gain access to, then press and hold the power button until the computer shuts down. Turn the computer back on and enter BIOS at startup. Change the boot sequence to CD before HDD, then save and exit.

The computer will restart and Ophcrack will be loaded. Sit back and watch as it does all the work for your. Write down the password it gives you, remove the disc, restart the computer, and log in as if it were you own machine.

Mac

The second most popular operating system, OS X is no safer when it comes to password cracking then Windows.

The easiest method would be to use Ophcrack on this, also, as it works with Mac and Linux in addition to Windows. However, there are other methods that can be used, as demonstrated below.

If the Mac runs OS X 10.4, then you only need the installation CD. Insert it into the computer, reboot. When it starts up, select UTILITIES > RESET PASSWORD. Choose a new password and then use that to log in.

If the Mac runs OS X 10.5, restart the computer and press COMMAND + S. When at the prompt, type:

fsck -fy

mount -uw /

launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist

dscl . -passwd /Users/UserName newpassword


That’s it. Now that the password is reset, you can login.

Linux

Finally, there is Linux, an operating system quickly gaining popularity in mainstream, but not so common you’re likely to come across it. Though Mac and Linux are both based on Unix, it is easier to change the password in Linux than it is OS X.

To change the password, turn on the computer and press the ESC key when GRUB appears. Scroll down and highlight ‘Recovery Mode’ and press the ‘B’ key; this will cause you to enter ‘Single User Mode’.

You’re now at the prompt, and logged in as ‘root’ by default. Type ‘passwd’ and then choose a new password. This will change the root password to whatever you enter. If you’re interested in only gaining access to a single account on the system, however, then type ‘passwd username’ replacing ‘username’ with the login name for the account you would like to alter the password for.

Conclusion

There you have it – that is how simple it is for someone to hack your password. It requires no technical skills, no laborious tasks, only simple words or programs. The moral of the story? Encrypt your data to keep it safe. Don’t use only a password, but actually encryption, such as Blowfish or AES-128. There are a number of programs that can do this – TrueCrypt for Windows, or the native encryption found on Ubuntu, creating a disk image in Mac, etc.
