Are you concerned about the privacy of certain apps on your iPhone? Do you want to prevent others from accessing sensitive information or making unauthorized changes? If so, you’ll be glad to know that you can easily lock an app on your iPhone to add an extra layer of security.

Why Lock an App on iPhone?

Locking an app on your iPhone is a great way to protect your personal data and maintain privacy. It can be especially useful if you share your device with others or if you often lend it to friends or family members. By locking specific apps, you can ensure that only authorized users have access to them, providing peace of mind and safeguarding sensitive information such as personal messages, photos, or financial details.

How to Lock an App on iPhone

If you’re wondering how to lock an app on your iPhone, follow these simple steps:

Step 1: Enable Screen Time

The first thing you need to do is enable Screen Time on your device. Screen Time is a built-in feature in iOS that allows you to monitor and control the usage of various apps.

To enable Screen Time, go to Settings, Screen Time, and tap Turn On Screen Time. You may need to set up a passcode for Screen Time if you haven’t already done so.

Step 2: Set a Passcode

To lock individual apps, you’ll need to set a passcode within the Screen Time settings. Go back to the main Screen Time menu and tap Use Screen Time Passcode. Enter a strong passcode that only you know and remember.

Step 3: Lock the Desired App

Once your passcode is set, you can proceed to lock the specific app you want to secure. Open the Settings app and navigate to Screen Time.

Tap on App Limits and select Add Limit. From the list of apps, choose the one you want to lock and tap on it.

Step 4: Customize App Lock Settings

After selecting the desired app, you can customize the lock settings. You have the option to set a time limit for app usage or simply choose to block it completely.

To lock the app entirely, toggle off the All Apps & Categories option and tap Add 1 Minute. This ensures that whenever someone tries to open the locked app, they will be prompted for your Screen Time passcode.

Tips for App Locking on iPhone

To enhance your app locking experience on iPhone, here are some additional tips:

  • Create Unique Passcodes: Avoid using passcodes that are easy to guess or commonly used by others. Opt for a strong and unique passcode that is hard to crack.
  • Regularly Change Passcodes: To maintain maximum security, consider changing your passcodes periodically.

    This helps protect against potential unauthorized access.

  • Use Face ID or Touch ID: If your device supports Face ID or Touch ID authentication, consider enabling it for an added layer of security. This way, only your face or fingerprint can unlock locked apps.
  • Avoid Sharing Your Passcode: Keep your Screen Time passcode confidential and avoid sharing it with anyone else. Sharing your passcode compromises the effectiveness of locking apps on your iPhone.


Locking an app on your iPhone is a simple yet effective way to protect your privacy and secure sensitive information. By following the steps outlined in this article, you can easily lock any app on your device and prevent unauthorized access.

Remember to set strong passcodes, regularly change them, and consider enabling Face ID or Touch ID for enhanced security. With these measures in place, you can confidently lend your iPhone to others without worrying about compromising your personal data.
