How to Add Passwords to Text Files in Windows 11/10

Need to keep your notes, passwords, or private data safe in a text file? Windows 11 and 10 don’t offer built-in password protection for plain text files. But don’t worry—you have options, and you don’t need to be a tech wizard to lock down your files. Here’s how you can protect your text files from prying eyes.

Why You Need Password Protection

Text files are easy to open and edit, but that also makes them easy targets for anyone with access to your computer. If you want to keep sensitive info private, adding password protection is a smart move.

Option 1: Use 7-Zip (Free and Easy)

7-Zip is a free tool that lets you compress and password-protect files, including text files.

Steps:

1. Download and Install 7-Zip:
   Get it here.
2. Find Your Text File:
   Right-click the .txt file you want to protect.
3. Add to Archive:
   Select 7-Zip > Add to archive…
4. Set a Password:
   In the window that pops up, set an archive format (like .zip or .7z), then enter your password in the “Encryption” section.
5. Click OK:
   7-Zip will create a new compressed file. Delete or securely store the original unprotected file.

Note: Anyone who wants to open the file will need the password.

Option 2: Use Microsoft Word (For Simplicity)

You can copy your text into a Word document and use Word’s built-in password protection.

Steps:

1. Open Word and paste in your text.
2. Go to File > Info > Protect Document > Encrypt with Password.
3. Enter and confirm your password.
4. Save the document.

Option 3: Use Notepad++ Plugin

If you use Notepad++, you can add a plugin for encryption.

Steps:

1. Open Notepad++
2. Go to Plugins > Plugins Admin…
3. Search for NppCrypt and install it.
4. With your text open, go to Plugins > NppCrypt > Encrypt.
5. Set your password and click OK.

Quick Tips

• Don’t forget your password. If you lose it, your file may be unrecoverable.
• Back up your files. Store backups in a safe place in case something goes wrong.
• Avoid third-party tools from unknown sources. Stick to reputable software to stay safe.

Bottom Line

There’s no native way to password-protect .txt files in Windows 11/10, but free tools like 7-Zip, Microsoft Word, or Notepad++ plugins make it easy. Take a few minutes now, and keep your info locked down.
