#1 Password Protect Folder on Mac Using Disk Utility
Disk Utility is an in-built macOS app for managing disks, drives and partitions. As it happens, it also lets you create a password-protected folder in your Mac. It is not a folder, per se. But, you can easily manage all your files. Let’s have a look at the steps now.
Step 1
First, we have to open Disk Utility app on Mac. You can simply search via Spotlight or find it in Utilities subfolder of Applications.
Go to File > New Image > Image from Folder. Alternatively, you can press Shift+Command+N
Step 2
Now, you have to select the folder that you want to password protect.
Step 3
In the upcoming window, you have to select a few things such as the name and security type.
Give the name for the password-protected folder
Provide some tags and select the location where you want to save it
For encryption, choose 128-bit AES Encryption and provide the password
For Image Format, you have some choices, such as Compressed, read/write, hybrid image and read-only. Choose one of them
Once you are done, click the Save button.
Step 4
Depending on the size of the folder, the encryption process may take some time. Once you get the confirmation message, go to the location where you saved the image.
Type the password and click Okay.
Now, you can see a virtual disk with the same name of the folder. Open it to see the files and access them.
After the use, Eject the drive to make sure that no one else can access the folder.
Note: If you had selected read/write for Image Format, you will be able to copy and paste files easily. But, it depends on what kind of protected folder you want.
You can count on this method if you need something native. As you see, we don’t need a third-party app to protect folders on Mac using Disk Utility.
#2 Password Protect Mac Folders Using Hider
If you want to password protect folder in mac without disk utility, then third-party apps are better option.
Macpaw Hider is an popular app to enable password protection for folders and files. However, it does work like having a secure space inside your Mac. Hider is a paid software (starts at $19 for single license) but you can check out the free trial for 15 days.
You can use this method to encrypt and protect folders, files and secure notes. It also has an impressive UI to make things cool. Once you are installed, you can add whatever you want to protect into the Hider 2 UI. It also offers an option to hide the document/folder.

This is the best thing we loved: once you close Hider 2, everything is secure. You have to enter the password to access contents from the Encrypted folder. Hider 2 is a premium software and it comes at $19.95 for one license.
You can try this method if you need a more accessible way to password-protect files and folders. You cannot use this method if you want to send/transfer the locked content.
#3 Encrypt Files via Terminal, using OpenSSL
Here is another built-into-Mac method to protect your folders and files. You should use this method if you want to add files to encrypted folder in Mac. We are going to do this using Terminal and it involves some code. If you would, let’s have a look at the steps.
Step 1
Open Terminal on your Mac and enter the following command.
Now, in this command,
openssl and aes-256-cbc designates the encryption type.
–in ~/Desktop/Photo.jpg designates the file you want to encrypt and its location
-out ~/Desktop/Encrypted.file designates the location where the encrypted file would be saved
Step 2
Enter the command and provide the encryption password when asked
Confirm the Password to continue
Step 3
Now, you can see the Encrypted.file document on your Desktop. Depending on your need, you can change the directory and encryption methods
Note: To decrypt the same file, enter the following command
Make sure you change the file-names and add ‘-d’ without quotes.
As we said earlier, you can use this method to encrypt and protect individual files. Since everything can be managed via Terminal, you don’t need a third-party software. Well, the limitation is, you can’t do it for folder.
#4 Use Concealer to Password Protect Files, Folders and More
Concealer is an advanced Mac app that lets you encrypt and store files and folders. In addition, you can take care of sensitive documents like Notes, Credit Card and software licenses. All of these are protected by one master password.

In addition to that, Concealer allows you to set individual password for stored files as well. Just like we said in the case of Hider 2, it also uses 256-bit encryption. Once closed, everything is clean. Without the master password, whatever you stored in Concealer will be inaccessible.
There are also some other smart features that may interest you. But the point is that you can simply drag-n-drop files and encrypt them with best security. Of course, don’t expect to share these files easily. Unlike the Terminal and Utility Disk methods, you should have Concealer app for encryption and decryption.
Concealer for Mac is available at a price tag of $19.99. However, there is a free trial version that allows you to save a limited amount of data.
#5 Password Protect Files Using Compression
Here is another method to protect files/folders via Terminal. However, we are going to compress the folder or file with a password. This way, the contents cannot be accessed without a password. But, since it’s a ZIP file, you can easily send/transfer it.
Let’s have a look at the steps.
You have to open Terminal and bring it to where you’ve stored the file. In my case, I had my files on Desktop.
Now, after the confirmation, you have to enter the following command.
Password Protect Entire Folder
So, this means the file Photo.jpg will be converted to a ZIP file named photo.zip. You have to provide a strong password after the command. Repeat the password and you’re done.
In a second or two, you can see the zipped file on your Desktop. Now, whenever someone tries to open the ZIP they will require a password to open a folder on Mac. Do one more thing: delete the original file, since the same is safe inside one ZIP file.
As you can see, this method works like a piece of cake. You don’t have to worry about anyone accessing the files, especially if you deleted the originals. Also, this password protection would work even if you transfer the ZIP file to somewhere else.
Bonus Tip
Want to prevent some folders from showing up via Spotlight? Here’s a method.
Add ‘.noindex’ after the folder name. If the folder name was Photos, make it Photos.noindex
The folder will not be shown in Spotlight search anymore. Keep it somewhere away and it’s a kind of safety.
Password Protect Folder on Mac
So, we have covered the 5 best ways to make a private folder on macOS. The first four methods use higher levels of encryption while the fifth one is compression. Anyway, it’s sure that others won’t have access to your files. If you ask us, Utility Disk is our favorite one. You don’t need a third-party app, but you have access to a read/write folder. Which one do you think you’d choose? Let us know in the comments.

You know who you are: a) your passwords are scribbled on a tattered and torn piece of paper right next to your computer; b) your spouse’s credit card number or social security number is on a post-it note next to the mouse; or c) you create a Christmas shopping list and save it on your desktop as “DO NOT READ.”
Save yourself the hassle of applying for a new social or ruining Christmas for everyone. You can create an encrypted, password protected folder on a mac without using any third-party software and it is done in just 5 easy steps – by creating an encrypted disk image.
1. Open Disk Utility by navigating to Applications > Utilities > Disk Utilities.
2. Choose File > New > Blank Disk Image or click the New Image icon.
3. In the New Blank Image window that appears, name the new secure folder or “image.” Next, choose your desired size from the pop-up menu that is sufficient to hold your super-secret data. Then, from the Encryption pop-up menu choose 128-bit AES Encryption (secure enough for all of us and faster than 256-bit). Finally, choose either read/write or Sparse Disk Image from the Image Format pop-up menu and click Create.
A read/write disk image takes up a set amount of space on the drive, while a sparse image is a type of disk image file that grows in size as the user adds data, taking up only as much disk space as stored in it.
4. At this point, you will be prompted for a password. Click one that is easy for you to remember, as a lost password means all the files on the image are lost too.
Remember to uncheck the ‘Remember Password in My Keychain’ option. Otherwise, anybody sitting down at your computer will have access to your image – which would defeat the purpose of this whole helpful article
Click OK and both the sparse image file and mounted image are created. This will look familiar to anyone who has put an external drive into their computer before.
5. Double click the image to mount the “folder.” Drag the content that you want to protect into the mounted image.
When you’re done with it, drag the mounted image to the trash to eject it or right-click it and choose “Eject.” When you next need it, double-click on the image file and enter its password when prompted.
With these 5 simple steps you can create a password protected folder on your mac. While this is an effective means of keeping data from the prying eyes of thieves or children, as explained above, it is far from secure as anyone can simply delete the image.
