How to Lock Apps on a Mac With a Password in 2026

Mac apps can contain private conversations, financial records, saved passwords, and work files. If you’ve been looking for a way to protect those apps when someone else uses your Mac, macOS makes the job more awkward than it should be.

macOS lacks a built-in setting that requires a password whenever a specific app opens. Screen Time can restrict an app after a short daily allowance, while AppLocker and AppCrypt provide a proper password prompt at launch.

Choose the Right Way to Lock Your Apps

The best method depends on the problem you need to solve:

• Use Screen Time when you want parental controls or a free productivity restriction.
• Use AppLocker or AppCrypt when you need a password prompt each time a protected app launches.
• Use separate macOS accounts when several people regularly share one Mac.
• Enable FileVault when theft or physical access is your main concern.

An app locker handles casual privacy on an unlocked Mac. FileVault and a strong account password protect the underlying data more effectively.

Lock Apps With Screen Time

Screen Time addresses this by blocking an app after its daily allowance expires. Set the allowance to one minute, enable blocking, and anyone who wants more time must enter the Screen Time passcode.

This method costs nothing and uses Apple’s own controls. The trade-off is that the app remains available until its one-minute allowance runs out each day.

Set a Screen Time Passcode

1. Open System Settings and select Screen Time.
2. Turn on Screen Time if it’s disabled.
3. Enable the option that locks Screen Time settings, then create a four-digit passcode.
4. Store the passcode somewhere secure. Avoid using the same code as your Mac login password.

The wording around the passcode setting can vary by macOS release and account type. Look for the control that locks Screen Time settings or requires a passcode before restrictions can be changed.

Add a One-Minute App Limit

1. In System Settings > Screen Time, select App Limits.
2. Turn on App Limits, then click Add Limit.
3. Expand the relevant category and select the app you want to restrict.
4. Set the daily allowance to 1 minute.
5. Enable Block at end of limit.
6. Click Done.

Open the restricted app and use it until the allowance expires. macOS will then display a Screen Time limit message. Further access requires the passcode or approval from the family organizer.

Screen Time solves the access problem well enough for children and shared family Macs. It’s weaker for sensitive work because protection begins only after the allowance expires.

Lock Apps With AppCrypt

AppCrypt locks selected Mac apps and websites. It asks for an AppCrypt password when someone tries to open a protected app, and some versions can record failed access attempts.

Check the current system requirements before installing it. Third-party security utilities depend on permissions that Apple occasionally adjusts between macOS releases.

Install and Configure AppCrypt

1. Download AppCrypt and move it into your Applications folder.
2. Open the app from Applications or Spotlight.
3. If macOS displays a security confirmation, verify the developer shown in the dialog and click Open.
4. Create an AppCrypt password.
5. Enable its startup option so protection begins when you sign in.

Keep AppCrypt’s startup option enabled. If the utility quits or fails to launch after login, its app restrictions may stop working.

Add an App to AppCrypt

1. Click the AppCrypt icon in the menu bar.
2. Open its main window and enter your password.
3. Select the App Lock section.
4. Click the add-app control, usually shown as + or Add App.
5. Choose an application and confirm your selection.

Quit the selected app if it was already running, then reopen it. AppCrypt should display its password prompt before allowing access.

Open or Remove an AppCrypt-Protected App

Launch the protected app from the Dock, Spotlight, Launchpad, or Finder. The launch method makes no difference; AppCrypt handles the request while its background process is running.

Enter the AppCrypt password when prompted. A correct password opens the app, while a failed attempt leaves it blocked.

If activity logging is available in your installed version, open AppCrypt’s records to review failed attempts. Treat camera capture and activity logs carefully on a shared Mac because they can create their own privacy concerns.

To remove protection, open AppCrypt, authenticate, select the app in the protected list, and use its remove control.

Lock Apps With AppLocker

AppLocker is available through the Mac App Store. It protects selected apps with a passcode and supports Touch ID on compatible Macs.

AppLocker is a better fit when you only need launch protection. AppCrypt adds website blocking and related controls, which can make its interface busier than necessary.

Configure AppLocker

1. Open the App Store, search for AppLocker: Passcode Lock Apps, and install it.
2. Launch AppLocker and create a password.
3. Open AppLocker from its menu-bar icon and authenticate.
4. Enable Start at Login or the equivalent startup setting.
5. Turn on Touch ID unlocking if your Mac and the installed AppLocker version support it.

Use a password you can recover safely. Third-party password-reset procedures vary, and forgetting it can create a tedious cleanup job.

Add and Open a Protected App

1. Open AppLocker from the menu bar.
2. Click the + control.
3. Select the app you want to protect.
4. Quit that app if it’s already open.
5. Launch it again and confirm that AppLocker requests your password or Touch ID.

AppLocker must remain active. Test it after restarting your Mac rather than assuming the startup setting worked.

Remove an App From AppLocker

1. Click the AppLocker icon in the menu bar.
2. Enter your AppLocker password.
3. Find the protected app.
4. Click the X or current removal control beside it.

Launch the app again to confirm that the password request has disappeared.

Other App-Locking Options

Several other utilities provide similar controls:

• Lock – Password Protect Apps focuses on password protection for Mac applications.
• iLocker Mac can protect apps, folders, and files with a password or Touch ID.
• LockIt provides app-level protection through a dedicated locking utility.

Prices, permissions, and supported macOS versions can change. Check the current App Store listing or developer requirements before paying, especially if your Mac runs a newly released macOS version.

I’d skip older utilities that lack recent compatibility information. A security tool with an abandoned background process creates more headaches than privacy.

Grant the Permissions an App Locker Needs

Modern macOS may require an app locker to receive Accessibility, Full Disk Access, or another privacy permission. Grant only the permissions requested for the locking feature you’re using.

Open System Settings > Privacy & Security, select the requested permission category, and enable the app locker. Restart the utility afterward if it still fails to intercept launches.

Some utilities may request screen-recording access for optional monitoring or capture functions. Review that request closely. App launch protection alone doesn’t always justify access to everything displayed on your screen.

Use Separate Accounts for a Shared Mac

A separate macOS account is the cleaner solution when another person uses your Mac regularly. Each account keeps its own documents, browser sessions, Messages history, and application data.

1. Open System Settings > Users & Groups.
2. Click Add User.
3. Authenticate with an administrator password.
4. Create a Standard account for the other person.
5. Lock your session with Control + Cmd + Q before handing over the Mac.

A Standard account prevents routine administrator changes without your password. It also avoids trusting an app locker to defend every private application while your own session remains open.

Turn On FileVault for Theft Protection

App lockers protect application launches while macOS is running. FileVault encrypts your startup disk and protects its contents when the Mac is shut down or locked.

Open System Settings > Privacy & Security > FileVault, then turn FileVault on. Save the recovery information somewhere separate from the Mac, such as an encrypted password manager or encrypted external drive.

FileVault won’t add passwords to individual apps. It solves the more serious problem of someone reading your data after stealing the Mac or accessing its storage.

Fix Common App-Locking Problems

The Protected App Opens Without a Password

Check whether the app locker is running in the menu bar. Then enable Start at Login, restart the Mac, and test the protected app again.

Also inspect System Settings > General > Login Items & Extensions. Confirm that the app locker’s background item is allowed to run.

The Locker Stopped Working After a macOS Update

Review System Settings > Privacy & Security and re-enable any permission the utility requires. Open the App Store or the developer’s updater and install the current version.

If the problem continues, remove the affected app from the protected list, add it again, and retest.

Screen Time Allows Access for One Minute

That’s the built-in method’s main limitation. macOS applies the minimum daily allowance before blocking the app.

Use AppLocker or AppCrypt when protection must appear on every launch.

You Forgot the Screen Time Passcode

Use the recovery option offered by Screen Time and authenticate with the associated Apple Account when prompted. The available recovery controls depend on how Screen Time was configured, especially for Family Sharing accounts.

Finder or System Settings Won’t Stay Locked

System apps can behave differently because macOS relies on them for core tasks. Support depends on the locker and the permissions Apple allows.

Protect your administrator account and give other people Standard accounts when you need to prevent settings changes. That’s more dependable than trying to block Finder.

Removing an Icon Didn’t Lock the App

Removing an app from the Dock only removes its shortcut. The app remains available through Spotlight, Launchpad, Finder, and other launchers.

Use Screen Time or a working app-locking utility to control access.

Which Method Should You Use?

Screen Time is the sensible first choice for parental controls and distraction blocking. The one-minute allowance makes it a soft lock, but it handles those jobs without another background utility.

Use AppLocker when you want straightforward password or Touch ID protection. Choose AppCrypt when website restrictions or access records also matter. Keep either utility running at login and test it after every major macOS update.

For a shared Mac, separate user accounts solve the broader privacy problem. Add FileVault, a strong login password, and automatic screen locking when the data matters more than the app icon. With those layers in place, you’re no longer dealing with an exposed session whenever someone borrows or handles your Mac.
