6 Ways to Lock Apps on iPhone

What to know

Apple doesn’t offer an official way to lock apps on the iPhone to secure them from prying eyes.
But you can use Apple’s Shortcuts app to create an automation or home-screen shortcut to lock sensitive apps.
You can also use iOS features like Guided Access, Screen Time, and Face ID to lock certain apps on your iPhone.

The ability to lock apps provides an extra layer of security to your device, especially when sharing it with your friends or family members. Although Apple doesn’t offer a straightforward way to lock apps, there are other ways you can use to lock apps on your iPhone.

Can you lock apps on your iPhone?

Yes and No. Apple doesn’t give third-party app developers the option to lock apps on your iPhone using the in-built passcode or biometric security except for a few. Hence, there is no in-built way of locking apps on your iPhone, and neither is there a third-party app available on the App Store that allows you to do so.

However, like everything tech, there are a few workarounds that allow you to lock any app on your iPhone regardless of the restrictions imposed by Apple. Here are the 6 workarounds that you can deploy if you value privacy and want to lock individual apps.

Use the search bar to search for “Ask for”. Tap on Ask for input once it shows up in your search results.
Tap on Text to select the password format for your locked apps. You can have a numeric password as well.

Note: The text format allows you to enter as many numbers as you wish, while the Number format only allows you to enter a single digit.
Tap on Prompt and enter the desired prompt you wish to see when you are asked for a password when opening a locked app.

Finally, let’s see how this shortcut operates. Tap on the newly created Facebook shortcut from your iPhone’s home screen.
As expected, you will be presented with a notification, asking you to enter the password. Enter this password and tap on Done.
You can now use Facebook.

Method 3: Lock first-party apps by restricting content

Apple comes equipped with the Screen Time feature that can be used to lock first-party apps.

Note: First-party apps are applications created by Apple.

The Screen Time feature can be used to block apps based on 2 factors: Time Limit and Content & Privacy Restrictions. In this section, we will cover how you can block first-party apps using the latter method. So, without further ado, let’s get to it.

Open the Settings app on your iPhone.
Tap on Screen Time.
Tap on Turn On Screen Time to set up the Screen Time feature.
Tap on Continue.
Tap on This is My iPhone.
Now, back in the Screen Time settings, tap on Use Screen Time Passcode.
Assign a suitable passcode for your Screen Time settings.
In the Screen Time Passcode Recovery window, enter your Apple ID credentials and tap on OK.
Back in Screen Time settings, tap on the Content & Privacy Restrictions option.
Enter your Screen Time passcode.
Make sure the Content & Privacy Restrictions toggle is enabled.
Tap on Allowed Apps.
Locate the app you want to lock and tap on the toggle button next to it. For this app, we will lock the Safari app.
Make sure the toggle button next to the app you want to lock is grey.
Now that the app is locked, let’s see whether you can access it without entering the Screen Time passcode.
It turns out, the Safari app is not accessible from your iPhone’s home screen.
To access the locked app, you have to visit Screen Time settings and make sure the locked app is allowed from the ‘Content & Privacy Restrictions’ settings.

Method 04: Lock an app by limiting screen time

Another method of locking an app on your iPhone is by limiting the allowed screen time on this app on a per-day basis. The ‘App Limits’ option present in the Screen Time settings allows you to set daily limits on any app you wish.

Once this limit is exceeded, you will be required to provide the Screen Time passcode if you want further access to this app, beyond the allotted screen time.

Let’s see how you can use the ‘App Limits’ option to lock an app on your iPhones.

Open the Settings app on your iPhone.
Tap on Screen Time.
Tap on Turn On Screen Time to set up the Screen Time feature.
Tap on Continue.
Tap on This is My iPhone.
Now, back in the Screen Time settings, tap on Use Screen Time Passcode.
Assign a suitable passcode for your Screen Time settings.
In the Screen Time Passcode Recovery window, enter your Apple ID credentials and tap on OK.
Back in Screen Time settings, tap on App Limits.
Tap on Add Limit.
Swipe down on your screen to see the search bar.
Search for the app you want to lock and tap on it. For this guide, we will add a Screen Time limit to the Facebook app. After selecting all the apps you want to add a time limit on, tap on the Add icon
Tap on Next.
Make sure that the Block at the End of Limit toggle is enabled.
Now, reset the time to 0 hours 1 min and tap on Add.
As you can see, App Limits on the Facebook app have been added.
Now, let’s see the application of these app limits. Open the Facebook app from your iPhone’s home screen.
After the set time (1min) has elapsed, you will be presented with the following window.
From here, you can tap on Ask For More Time to use Facebook for 1 more minute without having to enter the Screen Time passcode.
However, after this additional minute has elapsed, you will be required to enter the Screen Time passcode to use Facebook.
To use Facebook, enter the Screen Time passcode.
Tap on the option that suits you.
You can now reaccess Facebook.

Method 05: How to use Guided Access on iPhone

The Guided Access feature on iPhone works in an entirely different way. This option can be used to lock the current user in the app they’re using at the time guided access is triggered.

Once this feature is triggered, the user will be locked in the app. Unless they’re aware of the Guided Access Passcode, or somehow your iPhone can scan one of the registered Face IDs, the user cannot exit this mode.

This feature can be extremely useful when the primary user of an iPhone doesn’t want the secondary (the user they’re lending their iPhone to) to pry on any other apps on their iPhone other than the open one.

Let’s see how you can implement and subsequently use Guided Access on your iPhone.

Open the Settings app on your iPhone.
Scroll down and tap on Accessibility.
Under “General”, tap on Guided Access.
Turn on the Guided Access toggle.
Tap on Passcode Settings.
Tap on Set Guided Access Passcode.
Enter a passcode for using the Guided Access feature.
You can also link your Face ID with the Guided Access feature. Turn on the Face ID toggle button to enable it.
The toggle button will turn green upon enabling,
Now that Guided Access is enabled, let’s see how you can use this feature on the Facebook app. Open the Facebook app from your iPhone’s home screen.
Once the app is opened, press the Side button or the Home button from your iPhone 3 times to start the Guided Session.
A Guided Session also allows you to disable specific areas on your screen. To do so, tap and drag your finger over the area you want to disable. This will create a selection area that can be further resized according to your preference.
Now, tap on Start.
You will see a notification, informing you that the Guided Access Session has started.
You can now resume browsing Facebook in this isolated session, without having to worry about the user having access to other apps on your iPhone.
To exit this Guided Access session, triple-press the Side button on your iPhone.

Method 6: Lock specific apps from Settings [Banking apps]

While not all apps have this feature, some apps, specifically apps that require every inch of privacy and security they can provide to ensure the trust of users, have in-built options that require methods like passcodes, Touch ID, or Face ID to access these apps.

Some common examples of these apps that support Face ID are Banking apps like PayPal, BHIM, etc. Other apps like Google Drive and Outlook support Touch ID. You can find what apps installed on your iPhone have Face ID capabilities by following the below-mentioned steps:

Open the Settings app on your iPhone.
Scroll down and tap on Face ID & Passcode.
Enter the passcode if asked prompted.
Tap on Other Apps under “USE FACE ID FOR”.
Here you can see the list of apps that have used Face ID on your device.
From this list, you can toggle on or off an app’s access to Face ID fairly easily. To do so, simply disable or enable the toggle button next to this app to turn off or on this app’s access to Face ID.

Find out who opened apps on iPhone while you were away

You can modify the shortcut we created in the second method above to click a picture whenever a wrong password is used on your device to unlock locked apps. This can help you identify users trying to open the locked apps on your device. Follow the guide below to help you along with the process.

Note: You will require the shortcut we created in Method 02, to use this guide.

Open the Shortcuts app, locate the shortcut you created in Method 2, and tap on the 3-dots icon.
Tap on the search bar near the bottom of your screen.
Search for the Take Photo action and tap on it.
Make sure the camera option is set to Front. However, if it’s not, tap on Back and change it to Front.
In the “Take Photo” action, tap on more options.
Tap on the Show Camera Preview to disable it.
Note: Grey colored toggle button means the option is disabled. hence, make sure the Shoe Camera Preview toggle button is grey.
Drag and reposition the Take Photo action between the “Otherwise” and “End If” actions
Add another action called Save to Photo Album to your shortcut.
Drag and reposition this shortcut between the “Take Photo” and “End If” actions.
Finally, let’s see how this new shortcut operates.
Tap on the created Facebook shortcut from your iPhone’s home screen.
As expected, you will be presented with a notification, asking you to enter the password.
Now, if you enter the correct password, this shortcut will open the Facebook app. However, if a wrong password is entered, the shortcut will take a photo using the front camera and save it in the Photos app.
Once you get access to your device, you can then open the Photos app and use the most recent picture taken using the front camera to deduce the person who had tried, unsuccessfully, to open a locked app on your device. You can also disable notifications for the Shortcuts app to ensure maximum privacy. Use this guide by us to help you along with the process.
