Protect Your Passwords in Windows Files Easily

You can use text editors to keep private notes, codes, and other confidential data. They’re simple, easy to use, and don’t take many system resources. However, if you’re keeping these kinds of data on text files, you should protect them by adding passwords and encryption.

Unfortunately, Windows’ Notepadd app doesn’t let you password-protect its text files. Thankfully, third-party Windows apps allow you to add passwords and encryption to text files. LockNote, Secure Edit, and PeaZip are three free apps to protect text files with passwords.

This is how you can use these three apps to protect the information you save on text files in Windows 11/10.

How to Add Passwords to Text Files With LockNote

Steganos LockNote is a portable app that lets you create password-protected basic text files. You can also use it to apply passwords to existing text files, making it easier to protect your information.

So, this is how to use LockNote to protect your text information with a password.

Open the Steganos LockNote download page on Softpedia.
Click Download and select the Softpedia Mirror (US).
Next, open the Windows File Explorer and navigate to the folder where you downloaded the file.
Unzip the locknote-1.0.5-src+binary-win32.zip archive. You can check out how to unzip files on Windows if you’re unsure how to do this.
Open the extracted LockNote folder.
Double-click the LockNote application (executable) file to start the app.
Now you’ll see the welcoming message shown below within LockNote. Erase that message and input the text or notes you want to save.
Go to File > Save As.
In the Save As window, navigate to the folder where you want to save your file.
Input a title in the File name box, then click Save.
A password box will pop up. Enter matching passwords for the file in the two text boxes.
Click OK to save the file with the set password.

To open your password-protected text file, browse to the folder where you saved it and double-click the file. When you launch your file, a password box will appear; input the password you set and click OK to open it.

If you want to set passwords for an existing Notepad text file, open the folder that includes it, then drag and drop the Notepad file onto LockNote’s window. Select Yes on the dialog box that asks about converting files. Input a password for the file and click OK. That will save a duplicate LockNote file in the same folder as the original text file.

You’ll probably notice that the password-protected LockNote files have a .EXE file format. This means you don’t need to install the LockNote app to run your password-protected text file.

LockNote includes only limited text-editing options. However, you can at least select a few different fonts and sizes. To do so, click the View menu. Then you can click Font or Font size to choose alternative text options.

How to Add Passwords to Text Files With Secure Edit

Like LockNote, Secure Edit incorporates password and encryption features into your text file. However, it also lets you add images in PNG and BMP format. So, this is how you can add passwords to Windows text files with Secure Edit.

Open the Secure Edit Softpedia page.
Select Download Now and choose X86 or X64 to download the portable application, depending on your system. If you’re unsure, choose X86.
Open the File Explorer and navigate to the folder where you downloaded Secure Edit.
Double-click the SecureEdit64.exe file to open the text editor (no installation required).
First, input a password you want to add to the text file.
Input some content within the text editor.
Click Secure Edit’s File menu.
Select the Save as option.
Choose the Encrypted Files format on the Save as type menu.
Fill out the File name box.
Select somewhere to save your file.
Click Save.

Close Secure Edit and open the saved file. Go to the directory that includes the file you just saved with Secure Edit and open it.

You’ll probably need to choose an app to open the file with first because Windows doesn’t recognize the format. Click the More apps > Look for another app on this PC option. Select the SecureEdit64.exe file and click Open. You can then input the file’s password to open it within Secure Edit.
