8 Ways to Lock Apps on iPhone With Passcode or Face ID

Most of us would have already protected our smartphones with some sort of screen lock for security reasons so that no one can access the device. But then there are situations when you yourself hand over your iPhone to someone for some work and they start checking your private apps without even asking for your permission.

Lock apps on iPhone

Imagine how it would be if you can keep your apps private by locking them with a passcode or ID. Even if someone will have access to your iPhone, they won’t be able to access the apps you have locked. Locking apps on iPhone isn’t as simple and straightforward as it is for Android users. Android has several third-party apps for this task. But does iPhone also have such apps?

The app lock feature has still not made it to the iPhone and there isn’t a single third-party app that can find on the App Store, at least not for the non-jailbroken iPhones. In this article, we are going to share 2 simple workarounds for helping you lock apps on your iPhone or iPad behind the password wall. You won’t even need to install a third-party app as the iPhone already have some hidden features in the iOS system.

Method 1: Lock apps on iPhone using Screen Time

Screen Time is a feature on iOS that gives a detailed report about how much time you spend on your iPhone and provide tools to help you monitor and reduce your daily usage. There is a tool available in Screen Time called App Timer which allows you to set time limit on apps. Once the timer ends, it will lock the application with a passcode. Here’s how you can use Screen Time feature to lock apps on your iOS device –

  1. Open the Settings app on your iPhone/iPad.
  2. Find and click on the Screen Time option.

  3. If the Screen Time isn’t turned on, you will need to tap on Turn on Screen Time. Click the Continue button on the info page. Then you will be asked to choose if this is your own iPhone or your child’s iPhone. Choosing a child’s iPhone allows you to set up additional parental controls.
  4. Once you have activated Screen Time, click on the App Limits. Tap on Add Limit again and choose the app(s) you want to lock on your iPhone. You will see apps sorted in their respective categories. After selecting the app(s), click on the Next button to continue.
    Add apps to screen time
  5. Now you will be asked to choose the daily time limit for the apps you have selected. Since we are trying to lock the apps, we will choose the minimum time so the apps stay locked all the time. Set the time to 1 minute and click on Add option at the top-right corner.

  6. The next step is to set up a passcode for Screen Time. Click the Use Screen Time Passcode option and then enter a 4-digit number. Re-enter it again for confirmation. As for password recovery, you can provide your Apple ID (Email or Phone number). If you ever forgot the Screen Time password, you can use your Apple ID for recovery. You must set a different passcode than your screen lock, so even if someone knows your screen lock, they won’t be able to unlock your private apps.
    Use screen time passcode
  7. Now you have successfully locked app(s) on your iPhone. Whenever you will open them, you will see a locked screen asking you to enter the passcode.

Method 2: Lock iPhone apps with Guided Access

Guided Access allows you to lock your iPhone screen to a single app. Let’s say you are handing over your iPhone to someone and you don’t want them to have the freedom to open any other apps. In such a case, you can use Guided Access feature to make your iPhone stay locked to a particular application. Here’s a step-by-step guide –

  1. Open the Settings app and go to Accessibility.
  2. Under General sub-heading, click the Guided Access option.
  3. Slide the toggle button to the right to turn it on.

  4. Go to the Passcode settings and click on Set Guided Access Passcode. Enter a 6-digit password and re-enter it again to confirm. Make sure to use a different passcode than your screen lock as this will add an additional security layer otherwise there is no point in locking your apps separately. If you want to use the Face ID to lock your apps, you can enable the Face ID toggle.
  5. Now whenever you want to lock any app, simply press the side button of your iPhone three times and select the Start option at the top-right corner. This will activate the Guide Access and your iPhone will be locked to that particular app only.
  6. If you want to get out of the guided access mode, press the side button three times again. You will be asked to enter your passcode for verification. After that, choose the End option. That’s it!

Method 3: Lock apps on iPhone using Shortcuts

Another hidden hack to lock apps on your iPhone is by using the Shortcuts app. Shortcuts is a visual scripting application developed by Apple which allows you to create macros for performing automated tasks. You can create an automation in the Shortcuts app to lock apps on your iPhone with a passcode or Face ID. Here are the steps you need to follow –

  1. Open the Shortcuts app on your iPhone. It comes pre-installed on all Apple devices. If you have uninstalled it previously, install it again from the App Store.
  2. Go to the Automation tab and click the Create Personal Automation button.

  3. Find and select App. In the next screen, click Choose option and select the app(s) you want to lock. Make sure that the app automation is set to “Is Opened”. Click Next option at the top-right corner to continue.
    Create app locker automation
  4. Now tap the + Add Action button and search for Timer. Select “Start Timer” action.
    Add timer action to automation
  5. Set the timer to 1 second and tap the Next option.
  6. Now you will see the preview of your automation. Disable the “Ask Before Running” toggle. This is an important step. If you don’t disable this toggle, you won’t be able to lock the app. Once you have made all the changes, click the Done option finally. By now, you have successfully created an app lock automation using the Shortcuts app.
    Disable ask before running
  7. You need to do one more thing. Open the Clock app on your iPhone and go to Timer. Click the “When Timer Ends” option and set it to “Stop Playing”.
  8. To test if the automation is working, open the app you have locked. After a second, you will find that the iPhone has been locked automatically.

Method 4: Lock apps on iPhone with Face ID

You can also lock certain apps on your iPhone with Face ID. There is an option available in the Face ID settings where you can see all apps that have Face ID authentication available. A simple toggle switch lets you enable the Face ID for each app. Just follow these simple steps:

  1. Open the Settings app on your iPhone.
  2. Scroll down and select “Face ID & Passcode“.
  3. Enter your device passcode for verification.
  4. Now select “Other Apps” option under the “Use Face ID For” section.

Method 5: Enable password on iTunes & App Store

In this method, we’ll explore how to add an extra layer of security to your iOS device by enabling a password requirement for purchases and downloads from the iTunes & App Store. This added layer of protection ensures that only authorized users can make transactions and download apps on your iPhone. Here’s how to set it up:

  1. Launch the Settings app on your iOS device.
  2. Tap on your profile name at the top.
  3. Tap on “Media & Purchases” option. A pop-up menu will appear on your screen.

  7. Finally, tap the “Done” option in the upper-right corner to save the changes.

Method 6: Lock WhatsApp on iPhone

Some third-party apps have their own screen lock system. One such great example is WhatsApp. You can enable Face ID or Touch ID lock on WhatsApp from its built-in settings. Simply, open the WhatsApp on your iPhone and go to the Settings screen by clicking on the gear icon at the bottom-right corner. Now you need to click on the Account option and then go into Privacy settings.

If you want to lock any other app, check if there is a built-in screen lock feature on it. You can find such feature in the app settings. Unfortunately, some other popular apps like Instagram, Facebook and YouTube don’t have their own native feature for screen locking as of now.

Method 7: Lock Photos app on iPhone

To protect your private photos and videos from unauthorized access, you can use the built-in “Hide” feature in the Photos app. This will move your photos and videos to the “Hidden” album, so they won’t appear in your main Photos library.

  1. Open the Settings app on your iPhone.
  2. Find and tap on “Photos” app.

  7. Now you will be asked to verify your Face ID to view the hidden photos and videos.

A pop-up box will appear on your screen asking you to delete the app or remove it from the home screen. Select the second option. Please note that the app will still be available in the App Library and it can be also found using the search feature and Siri.
