How Do I Password Protect a Folder on Mac?

1. Open Disk Utility. For this, open Finder → Applications → Utilities → Disk Utility. Or, press Command + Spacebar to open Spotlight Search and type this app's name.
2. From the top menu bar, click on File → New Image → Image from Folder.
3. Now, select the desired folder you wish to lock and click on Choose.
4. Optional: For ‘Save As:' continue with the same name, or you may also change it. Click on ‘Where:' and choose the desired location to save the disk image. You can move it later as well.
5. Important: For ‘Encryption:' choose 128-bit AES encryption (recommended). The second option here (256-bit) is slower. Please enter the desired password, re-enter it to verify, and finally click on Choose.

You have successfully created a disk image (.dmg file) that is protected with a password. Now, let me show you how to use it.

How to View and Re-Lock the Password Protected Folder on Mac

1. Locate the .dmg disk file.
2. Double click to open it.
3. You will be asked to enter the password. Type the same password you used while creating the disk image and click OK. (Note: Do not check the box for ‘Remember password in my keychain.' If you do, it may defeat the purpose. The saved password will fill in automatically if someone has your Mac or knows its password.)
4. After you enter the password, you will see a disk image on the desktop. It looks similar to an external pen drive. Double click to open it, and you will see the contents in it.
5. Important: Now, delete the original folder so that the content inside it is removed from your Mac and is only available inside this password-protected disk image.
6. To re-lock the protected folder, right-click and choose Eject 'Folder Name.'
7. To reopen it, follow the same process from step 1.

Notes:

• This disk image will have almost the same capacity as the size of the original folder. You can freely delete existing content inside it and replace it with other content.
• Do not delete this .dmg file. If you do, everything will be lost.
• If you want to permanently remove the locked folder (and its contents), open Disk Utility, → choose the disk image from the left sidebar, → right-click on it, and choose ‘Delete APFS Volume.'
