In this article, I delve deep into how you can password protect your data and the many ways you can do data encryption. Read on to learn.

Can You Password Protect An SD Card?

If you own a digital device such as a smartphone or camera, you know that they run out of space most of the time because of their limited storage space capacity. This happens when you want to store items that require a high amount of space, like videos and photos.

Because of this challenge, most people use secure digital (SD) cards or memory cards for additional storage. However, what if your device is lost? Anyone can remove the SD card and misuse it unless you protect it with a password and encryption.

When others access your data, you have no idea what they will do with it. They can misuse the data by uploading your private information to third-party or public websites without your knowledge. However, you can avoid this by protecting the SD card with password and encryption. I’ll show you how to do it. Please read on.

How To Password Protect An SD Card?

To minimize a data breach, it is critical to password-protect files saved on the SD card. As a result, to protect the security of your SD card, you must encrypt it to prevent unauthorized individuals from accessing the data on it.

But what does it mean to encrypt an SD card? SD card encryption means that the files on your SD card are password protected, guaranteeing that no one else can access the data except you until you provide the correct password to unlock the SD card.

To lock your SD card, you choose a method depending on the version of Windows you are using on your computer. If your computer uses Windows 10/8/7 editions, they have an inbuilt encryption feature called Bitlocker that you can use to encrypt your SD card.

But if you are using other Windows versions, you can use third-party SD card encryption software.

Therefore, I will discuss how to encrypt SD cards using windows and third-party software to protect your files. Read on to learn.

How To Password Protect SD Card With Bitlocker

To begin, you must format your SD card using an NTFS, FAT16, FA32, or exFAT file system before encrypting it using Bitlocker. Furthermore, the Bitlocker encryption function is only accessible in Windows 10 Pro, not the Home edition.

The following are the steps you have to follow to encrypt SD card in Windows

  1. Insert your SD card and wait for Windows to detect it. If AutoPlay appears, select the Open folder to see files option.
  2. Select the SD card to encrypt from the ribbon. Then, select Turn on Bitlocker from the Manage menu.
    Alternatively, click This PC, then right-click on the SD card you wish to encrypt using Bitlocker and choose Turn on Bitlocker.
  3. The Bitlocker wizard will launch regardless of how you do it. The screen will appear; check the box labeled “Use a password to unlock the disk” and input the password twice. If you have a smart card, you may skip this step by selecting “Use my smart card to unlock the disk.”
  4. Following that, you are requested to create a backup of a recovery key, which will allow you to access the SD card if you forget the encryption password or misplace the smart card. Select one of the available options and follow the on-screen directions to save the key.
  5. If you opt to back up your recovery key using a Microsoft account, you must provide your Microsoft account email address and password. Then press the Next button.
  6. Here, you must specify how much of the disk to encrypt: Encrypt only utilised disk space, or encrypt the entire drive. If you’re unsure, I recommend encrypting the entire drive and then clicking the Next button.
  7. A screen will appear; select the Compatible mode option and then click the Next button.
    You’ve reached the stage where you can begin encrypting your SD card.
  8. To begin the encryption process, select the Start Encryption option. The length of time it takes to finish the operation is determined on the size of the SD card and the quantity of data on it.
