You can protect your Mac with a password or Touch ID, but what if you want to lock specific apps separately? There is no official Apple solution, but you can use a third-party app to get the job done.
We have found the free AppLocker utility as the best option for locking your apps. It is a simple menu bar app that allows you to password-protect apps with a password. You can protect an app for free, but you have to pay $ 9.99 to upgrade and unlock the limit and enable Touch ID and Bluetooth unlocking support.

Start installing the AppLocker app from the App Store on your Mac.
When you open the app, you will find a new icon in the menu bar. You will see a pop-up asking you to set a password. Click here on the "Set my password" button.
From the Preferences menu, create your password (something you will not forget) and if you have a MacBook with Touch ID, you can also use the " Enable Touch ID "tick. Now click on "Save password" and then click on the red Close button in the top left corner to leave the preference panel.
Go to the menu bar and click on the AppLocker icon. The drop-down list shows that the app is locked. Enter your password and click on the "Enter" button to unlock the app.
First check the "Start at login" option here. It ensures that AppLocker starts automatically every time you start up your Mac and locks all your selected apps. Second, click the plus sign (+) to add an app.
In the new window, look for an app on your Mac and then click it to add the program directly to the list with locked apps.
When you close the app and try to restart, AppLocker will ask for a password.
To remove an app from the locked list, return to the menu bar app, enter your password, and then click the "X" button next to the app's name.
AppLocker only works when starting an app. If an app is open and you return to it, it is still in the unlocked status. If you want to lock your apps daily, you must close the app when you walk away from your Mac. You can also use the "Command" shortcut with "+" to lock all apps immediately.
If you use the Apple Notes app, you must know that you can also protect individual notes with a password.
