Steps to Password Protect a Folder on Mac
Here we have given some steps to password protect a folder on Mac. Here are the steps:
- On your Mac’s Disk Utility app, open it. You can see it in the Applications > Utilities drawer, or you can search for it with Spotlight.
- In the Disk Utility app, access File via the menu bar and choose New Image > Image from Folder.
- Go to the folder you would like to password-protect, and click on it.
- You will be greeted with a dialogue box from which you can name your disk folder image, select save location, and configure options for encryption as well as the format.
- To encrypt your folder, select which encryption you would like to use from the Encryption drop-down menu; there are two choices: 128-bit AES encryption or 256-bit AES encryption. The latter choice provides better security features, albeit it will take longer to create and open the disk image.
- We will type the password after making the choice to encrypt. So make sure that you use a strong password, and bear in mind that this password will be used each time you need to open the folder. You can alternatively click on the key icon and this will produce a random password. In the text box, enter the password twice and click on Choose.
- Next, select read/write from the Image Format drop-down menu. This will enable you to modify your folder disk image by adding or subtracting files.
- Lastly, tap on Save to make your folder disk image. The amount of time that this will depend on the size of your folder.
- When the process is finished, Done. Now, inside the selected folder, a new file in .dmgextension will appear. This is your image of a password disc. Double-click on the .dmg file and type your password when asked to complete opening the password-protected folder. You will find a new volume mounted on the desktop as a disk image of your folder with the same name. You can open this volume and still access files as you have been doing.
- When you have finished working on your password-protected folder, be sure to eject the volume by clicking on the icon with an arrow pointing up next to its name in Finder or on the desktop. This will re-lock the folder disk image, after doing so no one access it.
