How To Password Protect a USB Drive in Windows

Posted by Robert Hayes on July 13, 2019

USB drives are cheap, reliable, portable, and quick. They’re an ideal way to secure, store, share or back up files. They make a great platform for people who work on multiple computers in the course of a day; one drive has all their working files and programs and the user can just plug and play all day long. It’s no surprise that these drives are so popular with users at every level. However, the very portability and removability of the drives raises a legitimate security concern – someone can pluck that USB drive out of a machine and walk away with your life’s work (or worse, your passwords and financial records) in their pocket. How can you secure a USB drive with password protection?

Fortunately, Windows 10 has made this very easy. In this article, I will show you how to password protect a USB drive using Windows. I’ll also show you some other methods for protecting USB drives. There are basically three ways to protect data on a USB drive; all three methods rely on various encryption protocols to secure the data. You can either encrypt the entire drive, buy a secure flash drive, or encrypt individual files.

Password protect the entire USB drive

Protect the drive using BitLocker

The most straightforward way to protect the drive is to password protect the entire device. That way, everything on the drive is secured, and even if you add new content to the drive at a later date, it will also be protected. There are third-party encryption tools on the market that serve special needs, but for 99% of Windows 10 users, the built-in encryption tool is perfectly adequate. The Windows 10 tool is called BitLocker, and it works on all sorts of drives, not just removable USB drives.

Protecting a drive takes only a few seconds with BitLocker.

  1. Insert the USB drive into your computer.
  2. Navigate to This PC in Windows Explorer and right click the USB drive.
  3. Select Turn BitLocker On.
  4. Select ‘Use a password to unlock the drive’ and enter a password twice.
  5. Select Next.
  6. Select where or how you want to receive your recovery key in the next window and select Next.
  7. Select ‘Encrypt entire drive’ and then Next.
  8. Select ‘Compatible mode’ in the choose which encryption mode screen and then hit Next.
  9. Select Start encrypting.

The Explorer icon for the USB drive will now change to include a padlock. When you want to access the drive, double click it and you will be prompted for a password. Be sure to use a password you can remember, or write it down somewhere safe, because without your recovery key, that password, or a stack of supercomputers, you aren’t going to be able to decrypt the drive.

Protect the drive using VeraCrypt

If you want to protect your drive but don’t quite trust Microsoft, you can use VeraCrypt, a similar software package from the software company Idrix. It is open-source and freely available; you can make donations to support the project if you use VeraCrypt. VeraCrypt actually has more features than BitLocker but is still fairly easy to use to protect a USB drive. As of September 2018, VeraCrypt is on release version 1.23.

Protecting a drive is a tedious process using VeraCrypt but it isn’t complex.

  1. Launch the VeraCrypt app by typing “veracrypt” in the search box, selecting the app, and hitting return.
  2. Click on “Create Volume”, select “Encrypt a non-system partition/drive” and click “Next”.
  3. Select “Standard VeraCrypt volume” and click “Next”.
  4. Click “Select Device” and select your USB drive from the list of devices that appears, then click “OK”, then click “Next”.
  5. VERY IMPORTANT: Select “Encrypt partition in place”. If you select the other option and there is data on your drive, the data will be overridden and lost. Click “Next”. If you are protecting an empty drive, select “Create encrypted volume and format it” and click “Next”.
  6. Select the encryption method and hash algorithm you wish to use. This is technical; you can pretty much choose any of these and it will be fine unless the NSA is coming after your data. Click “Next”.
  7. Confirm the volume size and click “Next”.
  8. Enter and confirm your password, and click “Next”.
  9. Decide whether you will have large files on this partition or not, and select appropriately. Click “Next”.
  10. This is a rather fun bit. Move the mouse randomly around in the window while VeraCrypt randomizes the cryptography. Your mouse movements apparently add randomness to the keys the program selects. Move them around until the bar is green, then click “Format”.
  11. Confirm the format command and wait. This process will take a few minutes to an hour or more, depending on the size of your drive, the data already on it, and the speed of your computer.
  12. Mount the formatted drive in VeraCrypt (entering the correct password) and your drive will now be encrypted and functional.

Buy a secure USB drive

If you don’t use Windows 10, or would rather buy a USB drive with hardware-based security, there are options available. The market offers a range of secure options for encrypted USB drives. Some will have physical keys on the casing for protection while others will require a software key to unlock. The advantage of a secure USB drive is that they can include military grade encryption. The downside is that they are bulky and expensive. Where you would typically pay $10 for a normal 32GB USB drive, you can pay in excess of $130 for the same capacity secure drive.

Unless you need military grade encryption or a specific hardware solution, I would stay away from these secure USB drives. It’s hard to justify the cost when you could buy a standard drive for a few dollars and then use VeraCrypt or BitLocker to provide data security. VeraCrypt took over from TrueCrypt, an open source encryption program that is very effective and easy to use. I would suggest using VeraCrypt if you don’t have the Pro or Enterprise version of Windows for encrypting the entire USB drive.

Password protect files on a USB drive

If the drive itself doesn’t need to be secured but a specific file or directory does, then you can use Windows’ built-in password protection to secure the files, or use a file compression tool to password-protect it. For example, you can password protect most Microsoft Office documents individually. Open the document, select File, Info and Protect Document from the menu options. Select the option to Encrypt with Password. Add the password and then save it. From that point onward, every time you try to open the document you will be prompted for that password.

If you don’t have the option to use built-in encryption, you can use WinZip or WinRAR to compress the file and password protect it. Right click the file and select Add to Archive or Send To Compressed folder. Select the option to Set password or password protect, enter and confirm the password and compress the file. Every time you want to access the file, you will be prompted to enter the password before it is decompressed.

Those are three simple but very effective ways to password protect a USB drive in Windows. Got any other suggestions? Tell us about them below if you do!

Actually, as of the date of this article, yes, yes it does. You’ll need the current version though… Try updating.

BitLocker isn’t included in Windows 10 Home edition. I suggest you to mention this in your article.

This doesn’t work with Windows 10 Home edition, as Bitlocker isn’t included. This needs to be clarified in your article. Thanks anyway.
