How to Lock an App on iPhone: Protecting Your Privacy and Data


Privacy and data security are paramount in today’s digital age. With the increasing use of smartphones, we often store sensitive information on our devices. To add an extra layer of security, you can lock individual apps on your iPhone. This article will guide you through the steps to lock an app on your iPhone using built-in features and third-party apps.

Method 1: Use Guided Access (Built-in Feature)

Apple’s Guided Access feature is a built-in tool that allows you to lock your iPhone to a single app, making it an excellent choice for those who need to lend their phone or want to restrict access to specific applications.

Here’s how to enable Guided Access:

  1. Enable Guided Access: Go to “Settings” on your iPhone, tap “Accessibility,” then scroll down and select “Guided Access.” Toggle the switch to enable it.
  2. Set a Passcode: After enabling Guided Access, set a passcode. This passcode will be required to exit Guided Access mode.
  3. Start Guided Access: Open the app you want to lock, press the side button (or home button, depending on your iPhone model) three times quickly. This activates Guided Access.
  4. Configure Settings: You can adjust settings like time limits and touch options for the locked app. Once set, tap “Start” in the top-right corner.
  5. Exit Guided Access: To exit Guided Access and unlock the app, triple-click the side (or home) button again and enter the passcode.

Method 2: Use App Lockers (Third-party Apps)

There are various third-party apps available on the App Store that provide more advanced options for locking individual apps. Here, we’ll use an app called “AppLocker” as an example.

Here’s how to lock an app using AppLocker:

  1. Download AppLocker: Visit the App Store and download “AppLocker.” Install and open the app.
  2. Set a Passcode: The first time you open the app, you’ll be prompted to set a passcode. This passcode will be used to unlock your locked apps.
  3. Choose Apps to Lock: In AppLocker, you’ll see a list of your installed apps. Tap the ones you want to lock, and a padlock icon will appear next to them.
  4. Accessing Locked Apps: When you or someone else tries to open a locked app, you’ll be prompted to enter the AppLocker passcode.
  5. Additional Features: AppLocker also offers additional features like a fake crash screen and app usage tracking.

Method 3: Use Screen Time (Built-in Feature)

Screen Time is another built-in feature on iOS that can help you lock apps. It’s typically used for parental controls and digital well-being, but you can leverage it to restrict access to specific apps as well.

Here’s how to lock an app using Screen Time:

  1. Set Up Screen Time: Go to “Settings,” tap “Screen Time,” and set it up if you haven’t already.
  2. Downtime: Under “Screen Time” in “Settings,” go to “Downtime.” Set a schedule when you want to restrict access to specific apps.
  3. App Limits: You can also use “App Limits” to set daily time limits for specific categories of apps. This indirectly restricts app usage.


Protecting your privacy and data is crucial in today’s digital world. Locking apps on your iPhone is an effective way to ensure your sensitive information remains secure. You can use built-in features like Guided Access and Screen Time, or you can opt for third-party app lockers, depending on your specific needs and preferences. By following the steps outlined in this guide, you can gain better control over who can access your apps and when they can do so, enhancing your overall device security.
