How To Password Protect Files On Mac
If yоu store any kind of сonfidential files on your Mac, It’s highly recommended that уou add password protection to your files so they can’t be accеssed bу any unauthorized users. Password protection becomes more useful when you haνe other pеople accessing your Mac machine.
Your Mac provides you with an easy way to add password protection to your files. There are built-in tools that let you password protect your files from prying eyes with extreme ease. Once your files are protected, they’ll require a password before they can be accessed by anyone.
Bear in mind though, if you ever forget the password for your files, you won’t be able to access them again. There’s simply no recovery method available for these locking tools.
Password Protect Mac Files Using Disk Utility
Disk Utility is actually there to help you play around with your Mac disks. However, it has an option for locking files as well to help you add a layer of password to your files.
The way you password protect your files with this tool is to create an image file containing your files and then add a password to it. This locks your files down and these files can then only be unlocked by entering the correct password.
Make sure to put all the files you want to lock in a single folder on your Mac.
- Click on Launchpad in the Dock, search for and click on Disk Utility, and the tool will launch.
- When the tool launches, click on the File menu at the top and select the option that says New Image followed by Image from Folder.
- Navigate to the folder where the files to be locked are located, select the folder, and click on Choose.
- You’ll get a dialog box on your screen asking you to input the information for your new image file. Enter a name for your image file and then select 128-bit AES encryption (recommended) from the Encryption dropdown menu.
A new dialog box will appear asking you to enter the password for your image file. Here type in the password you want to protect your files with and click on Choose.
You’ll be back to the first dialog box. Click on the dropdown menu for Image Format and select the value that says read/write. This will let you add new files to your password-protected image file at a later time. Click on the Save button to save your image file.
You’ll find the locked image file at the destination you specified in the dialog box.
All of the files that have been put inside this image will be encrypted with a password.
Keep in mind though that this procedure hasn’t modified any of your original files and those still remain unprotected. You may want to securely delete them from your Mac as those are now available in your locked image file.
