How To Lock Apps On iPhone 15: A Complete Step-by-Step Guide

Locking apps on iPhone 15 is easy using built-in tools. The fastest way is to use Screen Time to set app limits with a Screen Time passcode, which forces a passcode or Face ID when the limit ends. You can also use Guided Access to lock an app while someone else uses your phone, or lock specific notes and apps that have their own passcode settings. Follow the steps below to set up Screen Time app limits and secure the apps you want.

Tutorial – How To Lock Apps On iPhone 15

These steps will show you how to use Screen Time on your iPhone 15 to require a passcode or Face ID when someone tries to keep using an app past a short time limit.

Step 1: Open Settings and tap Screen Time.

Open the Settings app, then find and tap Screen Time to begin.

Tap Screen Time and you will see options like App Limits and Content & Privacy Restrictions. If Screen Time is off, tap Turn On Screen Time and follow the quick prompts to enable it for this device.

Step 2: Tap Use Screen Time Passcode.

Set a separate Screen Time passcode that is different from your device passcode.

Choose Use Screen Time Passcode, then create a four-digit or six-digit code. This code is what blocks apps after the limit, so keep it secret and do not use your device unlock code.

Step 3: Tap App Limits, then Add Limit.

Choose the apps or categories you want to lock and create a new limit for them.

Tap Add Limit, pick a category or expand it to select specific apps, then tap Next. You can select one app or many at once depending on what you want to protect.

Step 4: Set the limit time to one minute and enable Block at End of Limit.

Pick a very short time like one minute and switch on Block at End of Limit to force the lock.

Setting one minute makes the limit take effect almost immediately, so the app will ask for the Screen Time passcode or Face ID when time runs out. Block at End of Limit stops the app from opening without your permission.

Step 5: Test the locked app.

Open the app you limited and use it until the timer runs out to confirm the lock works.

After about one minute the app shows a screen saying time limit reached, and you must tap Ask For More Time and enter the Screen Time passcode to continue.

Step 6: Manage exceptions and Always Allowed apps if needed.

If an app must stay unlocked all the time, include it in Always Allowed from the Screen Time settings.

Go back to Screen Time and tap Always Allowed to add apps that should bypass limits, like Phone or Messages. Keep this list short so you do not accidentally allow apps you wanted to lock.

After completing these steps your chosen apps will prompt for the Screen Time passcode or Face ID after the short limit ends, effectively locking them from casual use.

How To Lock Apps On iPhone 15 Tips

• Use a one minute limit so the lock activates almost right away while still using the built-in Screen Time workflow.
• Make the Screen Time passcode different from your device passcode to prevent easy bypass.
• Use Guided Access for one-off situations when you want to lock the phone into a single app temporarily.
• Lock individual Notes or apps that include a built-in lock option, like Notes or some banking apps.
• Hide apps from the Home Screen to reduce accidental access, by removing them from the home pages and keeping them in the App Library.
• Regularly review Always Allowed to ensure you are not unintentionally exempting sensitive apps.
• Teach trusted family members the Screen Time passcode only if you want them to override limits.
• Keep iOS updated, because Apple may add new locking features in future updates.

Frequently Asked Questions

What exactly does Screen Time blocking do on iPhone 15?

Screen Time blocking stops an app from being used after the set limit. When the limit ends the app shows a time up screen and requires the Screen Time passcode or Face ID to continue, so casual users cannot keep using it.

Can I lock any app on iPhone 15 with this method?

Yes, you can apply App Limits to most third-party apps and many system apps. Some core system features, like Phone, are typically allowed and may need special handling under Always Allowed or Content & Privacy Restrictions.

How does Guided Access differ from Screen Time for locking apps?

Guided Access locks the device into one app so a person cannot leave that app until you end Guided Access. It is good for lending your phone or keeping a child in one app. Screen Time applies timed locks and works in the background for everyday protection.

Can someone override Screen Time limits without the passcode?

Not without the Screen Time passcode. They can request more time but must enter the passcode. If they know your device unlock code but not the Screen Time passcode, they still cannot bypass the app limit.

Is there a way to lock apps using Face ID only?

Screen Time will accept Face ID to approve more time if you have Face ID enabled for unlocking the device and you configured Screen Time to allow Face ID. App-specific locks that support Face ID, like Notes, will use Face ID directly.

What if I forget my Screen Time passcode?

If you forget the Screen Time passcode you can reset it using your Apple ID if your device is on a modern iOS and you set that option. If that does not work you may need to reset the device settings or contact Apple Support for help.

Summary

1. Open Settings, tap Screen Time.
2. Set a Screen Time passcode.
3. Add an App Limit.
4. Set time to one minute and enable block.
5. Test the app lock.
6. Adjust Always Allowed as needed.

Conclusion

Learning How To Lock Apps On iPhone 15 gives you control over who can open sensitive apps and for how long. The Screen Time method is the most reliable built-in option Apple provides for locking apps, and with a one minute limit you get an almost immediate lock without installing anything else. Guided Access is a helpful companion when you need to hand your phone to someone and keep them inside a single app. For apps that already have a lock option, say Notes or certain banking apps, use their built-in locks along with Screen Time for layered protection.

Make sure you choose a Screen Time passcode you do not share lightly. This separates app control from your normal unlock code and prevents casual overrides. Regularly review which apps are Always Allowed so you do not accidentally leave a sensitive app unlocked. If you are managing a child’s device, combine App Limits with Communication Limits and Content & Privacy Restrictions for a stronger setup.

If you want more privacy, consider hiding apps on Home Screen pages or using Focus modes to limit visibility during certain hours. Keep iOS updated because Apple often refines parental controls and privacy settings. Try the steps above, test them, and adjust time and apps until you have the right balance of security and convenience. If you run into trouble, Apple Support can guide you through Screen Time resets and passcode recovery. Give it a try now and lock down the apps that matter most.
