How to Password Protect USB Drive in Windows
 

We’ve come to a point when USB Drives not only portable but it can store a lot of important data. Apart from storing data in a USB flash drive, you can even use it as a bootable installation media device, to install OS. Undoubtedly, USB Drives are useful in so many situations, especially it is convenient for those who work on multiple computers. However, USB Drives portability raises a security concern – anyone can plug it in a smartphone and PC and can steal important data of yours.

Buying an encrypted USB drive with hardware encryption can be a solution. But, do you know, by using some free disk encryption software, you can achieve hardware-level encryption. Yes, there are some freeware applications to password protect USB drive in Windows, Mac OS, and Linux. In this article, I will tell you how to put a password on USB flash drive and encrypt individual files.

Password Protect USB Drive in Windows.

BitLocker. (Windows)

Before moving to some third-party encryption tools, first, I would like to introduce you to BitLocker. It is a Windows built-in full volume encryption feature. By default, It uses the AES encryption algorithm in cipher block chaining. Or, XTS mode with a 128-bit or 256-bit key. In Windows 10 November Update (Version 1511), Microsoft introduced a new encryption mode (XTS-AES). This mode provides additional integrity support but doesn’t support an older version of Windows. BitLocker lets Windows users password-protect internal and external drives. Means, it works on all sort of devices. And, it is free and quite easy to use.

Important: Windows 10 Home Edition doesn’t come with the BitLocker feature. Hence, if you’re using Windows 10 Home, then I suggest you skip this and use the next method. All other versions of Windows 10 Pro, Enterprise and Education comes with BitLocker. If you’re not aware of your Windows 10 edition, then go to Control Panel > System and Security > System to check.

How to password protect USB flash drive by using BitLocker.

1. Insert USB Drive into your Windows PC. (Create a backup of USB Drive, if there is any important data in it. The process to put the password on USB Drive by using BitLocker is simple and safe. But, it is always better to have a backup.)

2. Do open File Explorer, and Right-Click on the connected USB Drive, select the “Turn BitLocker On” option from the context menu.Turn on BitLocker

 

3. BitLocker Drive Encryption Windows will appear, select “Use a password to unlock the drive” option. And, enter and reenter your password and click on next.put a password on USB flash drive

4. Now, BitLocker will give you a few options to back up your recovery key. (In case, you forget your password, recovery key will be helpful.)backup your recovery key

You can either save to a file and upload that file to the cloud.

 

Or, can simply save to your Microsoft Account. (You can go with any option that you think is safe for you.)

5. Next, select the “Encrypt Entire Drive” option and click on Next.Encrypt Entire Drive - BitLocker

6. Now you have to select an encryption mode. If you’re going to use the password-protected drive in multiple PC’s, do select “Compatible Mode“. And, Click on next.Compatible Mode - BitLocker

A confirmation window will now appear, click on “Start encrypting“.

VeraCrypt. (Windows, Mac OS X, and Linux.)

If you don’t trust Microsoft’s built-in tool BitLocker, or you’re Windows 10 home user. Then you can use VeraCrypt. It is one of the best free open-source disk encryption utility. With VeraCrypt, you can create a virtual encrypted disk within a file. Or can encrypt a partition or the entire storage device. Though, protecting USB drive with the password in VeraCrypt is a tedious process, but, it isn’t very complex. That’s why I prefer the BitLocker. Make sure “Windows Fast Startup” is disabled. Though, VeraCrypt will give you options during the encryption process.

Note: Make sure there aren’t any important data on USB Drive.

How to password protect a flash drive using VeraCrypt.

1. Download Veracrypt Installer and extract it on a secure folder. After that, open the folder and run the VeraCrypt-x64 installer as administrator.Run VeraCrypt as administrator

2. Click on “Create Volume” and VeraCypt Volume Creation Wizard will get open. That will allow you to create an encrypted file container on the USB Drive. Or, you can encrypt the entire driver.

5. Next, Veracrypt will allow you to choose encryption and hash algorithm. I suggest you keep the default settings. Click on Next.

After that, confirm the volume size and, click on next.

6. Now, VeraCrypt will give you the option to put a password on the USB flash drive. Enter the password and click on next. (Do remember what you’re entering. Also, make sure in the password, there are 20 or more characters.)put a password on a flash drive

Next, It will ask you that you want to store files for more than 4 GB Size. I suggest you select “Yes” in it. And, hit the Next button.

7. Now, move the mouse pointer randomly. It is to increase the cryptographic strength of the encryption keys. Once the “Randomness Collected Mouse Movements” bar turns into green. Click on “Format” > Yes.Format Drive and Encrypt

That’s it, VeraCrypt will start creating encrypted Drive for you.

Ok, so these are the two tools to Password Protect USB Drive in Windows. That’s why, BitLocker is only for Windows, so for macOS and Linux, you have to use VeraCrypt. If you want to encrypt a file, then there are also some best file encryption software available. I will try to add more tools in this article.
