Knowing how to encrypt a folder on your computer adds an extra layer of security to private contents. This comes in handy in scenarios where you want to shut off prying eyes. The option for password protection will not pop up with a click on a folder; you must generate a protected folder. macOS omits native capability to incorporate password protection into folders.
So how to put password on folder mac? Creating a rudimentary password entails an encrypted disk image via the operating system’s Disk Utility tool. Once generated, you can access the folder in the form of a mounted virtual disk to modify, delete or add content after typing a designated password.
Any changes you introduce with the disk mounted will be automatically encrypted and password-secured upon yanking the disk to the Trash. To encrypt a folder, follow these steps:
Head for the macOS Disk Utility in the Applications folder or invoke the app via Spotlight. Once spotted, open the program.
Click on File in the Disk Utility toolbar, choose New from the sequential drop-down menu, and then Disk Image from Folder. Afterward, identify the folder you want to password protect in the resultant folder, selecting it, and hitting the Image button on the bottom-right edge of the window.
Alternatively, hunt down the folder with the search bar in the top-right corner and hit the Image button in the lower right corner of the screen.
After you tag and name the resultant files, choose read/write in the drop-down menu explicitly right of the ‘Image Format’ prompt. Next, select 128-bit AES encryption unraveled by the drop-down menu on the right of the encoding option. Now, select a preferred save destination and hit the Save button from the bottom-right edge when finished.
Once prompted, type and re-enter your chosen password in the spaces in the center of the pop-up window. Afterward, unselect the box on the left of Remember password in my keychain and hit the ‘OK’ key on the bottommost right of the window.
After creating the password-protected disk image, confirm it works like clockwork by attempting to access its components. Once you ascertain protection, erase the parent folder to make it inaccessible.
Your password-protected item will pop up in the Finder window in form of a .dmg file. Double-click to launch it. You’ll get a prompt to type your password after launching the file.
The disk image will throw up in the Locations on directly left of the Finder window after you launch it with the password.
Hit the folder’s name under the Locations set of options to view the contents in it. You may want to yank contents into the .dmg folder just like a regular one. You can also store new items into this directory.
Once you type the password, the disk image stays open in the Locations menu unless ejected. Right-click on the folder, select "Eject [folder name]" to exit the window. It will vanish from the Locations menu.
Another built-in folder protective option is invoking Terminal and it entails some code. It’s a game-changer when you want to throw in files to an encrypted folder on Mac.
Step 1: Launch Terminal on Mac and type the following command.
Under this flight path:
openssl and aes-256-cbc portray the encryption type.
–in ~/Desktop/Photo.jpg depicts the file you wish to encrypt and its destination.
-out ~/Desktop/Encrypted.file shows the source where the encrypted file is stored.
Step 2: Enter the command and feed the encryption password when prompted. Confirm the password to proceed.
Step 3: Afterward, you’ll access the Encrypted.file document on Desktop. Based on your demands, you can tweak the directory or encryption methods.
Use this technique to encrypt and shield individual files.
Compressing the folder with a password locks out all unauthorized snoops. However, it exists as a ZIP file making it transferable or shareable.
