If you’re like most people, you use your iPhone 8 to do a lot of things. You might use it to check your email, browse the web, or take pictures. But what if you need to keep some apps locked so that other people can’t access them? Here’s how to do it. To lock an app on your iPhone 8, first open the App Store and find the app that you want to lock. Tap on the app’s icon and then tap on “Settings.” Under “General,” tap on “Accessibility.” In the “Accessibility” section, tap on “Lock screen.” If you want to be able to unlock the app even when it’s locked, tap on “Unlock screen.” Then, under “Screen lock type,” choose one of the options: Password or Face ID. Finally, enter your password or scan your face with Apple’s new Face ID feature. If you want to disable locking altogether, uncheck both boxes under “Screen lock type.” ..
