How to Password Protect Folder on Mac with/without Disk Utility

If you have sensitive or personal information in a folder on your Mac or that you want to send via email, it’s important to protect it with a password. This article will guide you on how to password protect a folder on Mac using different methods. By locking a folder, you can ensure the files within it remain safe from prying eyes.

Method 1. How to Password Protect Folder on Mac with a Third-Party App

Applies to: macOS 10.13 or later

Although Mac provides the option to password protect a PDF or document and offers FileVault to encrypt your startup disk, it doesn’t have a built-in method to put a password on a folder. However, you can use third-party folder encryption software like F-Vault. F-Vault is a great app that allows you to password lock folders and files on your Mac.

Steps: How to Password Protect Folder on Mac without Disk Utility

  1. Download F-Vault from the App Store on your Mac.

  2. When you open F-Vault for the first time, set a password and provide your email for password recovery if needed.

  3. You will see the Vault and a default vault-folder named “Default.” You can also create new vault-folders.


  1. Drag the Mac folder that you want to protect into the Vault or a vault-folder.

  2. When prompted to delete the original files, click Delete.

Now your folder is protected with a password. The folder and its files are encrypted and can only be accessed by entering the correct password. They won’t appear in the search results when using Spotlight or Finder. To access the folder and its files, open F-Vault, enter the password, and click OK. To make them inaccessible again, quit F-Vault.

If you no longer want to keep a folder private, you can remove password protection by dragging it out of F-Vault to a desired location or by selecting the folder, control-clicking it, and choosing Export to Finder.

Applies to: All macOS versions

If you want to encrypt the folder itself without using Disk Utility, you can use Terminal, the free terminal emulator built into macOS. With Terminal, you can turn a folder into a password-encrypted ZIP archive file, which can be useful when sending a password-protected folder via email.

  1. Launch Terminal on your Mac. You can use Spotlight to search for it or go to Finder > Applications > Utilities.

  2. Control-click the folder you want to password protect in Finder, choose Get Info.

  3. In the Info window, go to the General section, highlight the location path, and copy it.

  4. Return to Terminal. Type cd (including the space), and paste the path. Press the Return key.

  5. Type ls and press the Return key.

  6. Type zip -er "Test A". Replace “TestAProtected” with the desired name for the ZIP file. Hit Return.

  7. Set a password when prompted. Verify it and hit Return.

  8. Delete the original folder.

The original folder still exists on your hard drive with all its files.

The password-protected folder will appear as a disk image file. When someone tries to open it, a dialog box will ask for the password. Once the correct password is entered, the files within the folder will be accessible. To password protect the folder again, control-click the file in the sidebar of Finder and select Eject.
