Chances are good that you have some photos on your Mac that you don’t want other people to see. Typically, photos on Mac are stored in the Photos library and are viewed and managed via Apple’s Photos app. Photos app doesn’t come with a built-in lock, which means people with access to your Mac can easily access and view your photos. If you know how to password protect photos on Mac, you can prevent this. This article will show you how to lock photos on Mac, be it a MacBook Air, MacBook Pro or iMac, etc.

Mac’s Photos does offer a “Hide Photo” feature. And you will find how to use it in the article. Locking or hiding personal photos can help protect your privacy from prying eyes.

Method 1. How to lock Photos on Mac effectively with AppCrypt

You can easily and effectively lock Photos app using Cisdem AppCrypt, the best app locker and website blocker for Mac. Once locked, Photos can be opened only by you. This way, your photos are protected and can’t be viewed.

Method 2. How to password lock photos on Mac with F-Vault

Above is how to lock photos on MacBook Pro, MacBook Air or iMac, etc. by locking Photos app. You can also get the job done by putting a lock on your photos, or more precisely on your Photos library (where your photos are stored on Mac). This part talks about how to do this using a photo vault.

This article used to show how to use MacFort to make a secret photo vault on Mac to hide photos. MacFort is not officially available now, so I replace it with an app called F-Vault in this 2021 update of the article.

1. Download and install F-Vault.

2. The first time you open it, set a password.

set password

3. Optionally set an email to recover the password in case you forget the password.

4. You are presented with the Default vault. You can rename it to “photo vault for Mac” or something else.

5. Go to Mac’s Pictures folder. Drag your Photos library into the said vault.

drag library

6. When asked if you’d like to delete the original files, click Delete. Or, you can manually delete the library in Pictures.

Now the photos on your Mac are locked in the vault. The Photos library is hidden and protected. When you or someone else tries to open Photos app, it won’t open normally because the library can’t be accessed.

library can’t be accessed

If you have multiple libraries for Photos and want to protect all of them with password, you can drag them all into the vault.

To unlock your photos, open F-Vault (which requires entering the password) and drag your library from the vault back to the Pictures folder.

Note: If you are locking photos on MacBook with Touch ID, you can unlock with fingerprint, which is more convenient. To enable it, go to F-Vault’s Preference and turn on Enable Touch ID.

Method 3. How to password protect photos on Mac with Disk Utility

Instead of using a photo vault, you can also prevent access to your personal photos on Mac using Disk Utility, a free utility included with macOS. This method is less straightforward.

1. On your Mac, go to Finder and find your Photos library in the Pictures folder.

2. Create a folder in the Pictures folder and move your library into the new folder.

3. Open Disk Utility. In the top menu bar, select File > New Image > Image from Folder.

select File

4. Select the folder that you have just created. Click Choose.

5. Set a filename and select the destination location.

6. Click the Encryption dropdown menu and choose 128-bit AES encryption (recommended). Set a password.

the Encryption dropdown menu

7. Click the Image Format menu and choose the read/write option (or a different option based on your need).

8. Click Save. And Disk Utility will start creating an encrypted disk image, which can take seconds, minutes or longer, depending on the number of photos.

9. When the process is done, go to the Pictures folder and delete the folder (including the Photos library within it) created in Step 2.

Now the photos on your Mac are locked in the encrypted disk image (with the extension .dmg). It won’t be possible to view the photos in your library anymore until you remove the lock.

Here’s how to unlock photos and make them accessible again. Double-click the disk image, enter password and click OK. In Finder’s left sidebar, click the disk image under the Devices section. Move your Photos library into Mac’s Pictures folder.

enter password to unlock photos

Method 4. How to lock Photos on Mac with Screen Time

If your Mac is running macOS 10.15 Catalina or macOS 11 Big Sur, you can use the built-in Screen Time to help lock Photos app on Mac in order to keep your photos private from snooping eyes. Also available on iOS, Screen Time can help lock Photos on iPhone.

1. Open Screen Time in System Preferences or via Spotlight. If it is not yet enabled on your Mac, go to Options and turn it on.

2. Select the box before Use Screen Time Passcode and set a passcode. It will be used to lock your Photos.

set a passcode

3. In the left sidebar, choose App Limits. Click Turn On in the top right corner to enable App Limits. Click the plus icon in the lower left corner.

choose App Limits

4. Expand the Creativity category and select Photos.

select Photos

5. Set the minimum time limit of 1 minute on Photos for every day. Enable the option Block at end of limit.

Now open your Photos app for 1 minute. And a message will show up letting you know that the limit is reached. Screen Time is now locking Photos with the passcode. If anyone wants to access it, he or she will need to enter the passcode.

With this method, your Mac allows you (or someone else) to unrestrictedly access Photos for 1 minute. Therefore, you need to open Photos for 1 minute on a daily basis to trigger Screen Time to password protect Photos on Mac.

Note: Apple introduced the “One more minute” option for Screen Time in an update. If your Mac has the option, then this method doesn’t help much because extra access to your Photos is allowed without having to entering the passcode. If not, it remains helpful.

Bonus tips to keep photos private on Mac

How to hide photos on Mac

You can also keep photos private by hiding them in Photos app. Such a feature is built in to the app.

1. Open Photos on Mac.

2. Select one or more photos that you want to hide from others. Control-click and select Hide Photos.

The hidden photos will only be found in the Hidden album. You can choose to show or hide the Hidden album in Photos by going to the View menu at the top of your screen.

hide photos

This feature only hides photos and probably won’t prevent those who are Mac savvy. If you want to password protect hidden photos or lock photo albums, you can consider the methods described above. Nevertheless, the feature can be useful. For example, it allows you to show someone your photo collection without letting him or her see certain photos.

Restrict apps from accessing your photos

In addition to potential snoopers, you may also want to protect your photos from apps. Some apps may want to use your photos in order to offer certain features. If so, they will ask you for access, you can deny it. If this has already happened, you can stop the access.

1. In your Mac’s System Preferences, go to Security & Privacy.

2. Go to the Privacy tab.

3. Select Photos in the sidebar.

select Photos

4. Select an app and then click Quit Now to remove access.

Now the access to your photos is stopped.

Create a secret Photos library to store your private photos on Mac

Apple Photos allows you to create additional photo libraries. You can create a new library on an external hard drive with encryption function.

1. On your Mac, press and hold the Option key and open Photos by clicking.

2. Click Create New.

click Create New

3. Import the photos that you want to protect into the new Photos library.

4. Once you finish importing, connect your external hard drive with encryption to your Mac. Move the new library into it.

5. Eject the external drive.

Now your private photos are safe and locked away in the encrypted drive. No one but you is able to view them.


When you are away from your Mac, it’s possible for your colleagues, family, friends or others to open Photos and view all your pictures and videos. You can hide or lock the secret photos, depending on the level of privacy you need. In the article, I talk about the common methods on how to lock photos on Mac. I hope they are helpful. Some of the methods can also lock images stored in a normal Mac folder.

    I was going to consider buy the AppCrypt but then I noticed that it's so easy for anybody to just close eject the Appcrypt and then they can by pass typing a password. That's a flaw or am I missing something here

      Dear Ra God Bz,The only one reason why ejecting AppCrypt without password is that you have removed one of the four system applications which include Activity Monitor, System Preferences, Console and Terminal from the block list.
