Can I use Face ID for App Store?

Face ID is Apple’s facial recognition system that allows you to unlock your iPhone, iPad, or MacBook and authenticate purchases using your face rather than a passcode or fingerprint. Many iPhone and iPad users wonder if Face ID can be used to sign in to the App Store and make purchases.

What is Face ID?

Face ID is an advanced facial recognition system developed by Apple and introduced with the iPhone X in 2017. It uses advanced technology like a TrueDepth camera system and infrared camera to create a 3D map of a user’s face.

This facial map contains distinct features like the curves of your face, the shape of your eyes, nose, and mouth. Face ID uses neural networks to convert this map into a mathematical model that is stored securely on your device. Each time you look at your iPhone or iPad, Face ID uses this model to verify it’s really you.

Face ID is considered very secure as the chance of another person unlocking your device is about 1 in 1,000,000 with a single registered face. It works even in the dark and supports additional features like Animoji and Memoji.

How Secure is Face ID?

Face ID uses sophisticated technology to provide robust security for your device and transactions. Here are some key facts about Face ID’s security:

  • The TrueDepth camera captures accurate 3D facial data with over 30,000 invisible dots projected onto your face.
  • The data is used to create a detailed depth map and infrared image of your face.
  • A neural engine converts this data into a mathematical model and stores it securely in the Secure Enclave on your device.
  • Face ID confirms attention with eye tracking before unlocking to prevent spoofing.
  • All processing is done on device and images are never stored or sent to Apple.
  • The chance of a false match is estimated to be about 1 in 1,000,000.
  • Face ID data stays secure even after rebooting or restoring your device.

Overall, Face ID provides a very high level of security for personal device use and transactions.

Can I use Face ID for the App Store?

Yes, you can use Face ID to authenticate and make purchases on the App Store on supported devices like the iPhone and iPad.

When you first set up Face ID, there is an option to use it for App Store and iTunes Store purchases. If you enable this, you will be able to:

  • Download free apps
  • Make in-app purchases
  • Buy apps, music, movies, TV shows
  • Access your Apple ID account

Instead of needing to enter your Apple ID password or use Touch ID, you can simply confirm purchases and sign in with a glance using Face ID.

Setting Up Face ID for App Store

  1. Go to Settings > Face ID & Passcode on your iPhone or iPad.
  2. Enter your device passcode if prompted.
  3. Scroll down and make sure the toggle for “iTunes & App Store” is enabled under “Use Face ID For.”

Once enabled, you will now be able to use Face ID to download apps, games, and other content from the App Store.

Using Face ID in the App Store

Whenever you need to provide authentication in the App Store, Face ID will activate to confirm it’s you. Here are some examples:

  • Downloading Apps: Instead of entering your Apple ID password, you can download free apps by glancing at your device to confirm with Face ID.
  • In-App Purchases: When making purchases inside apps, Face ID will authenticate the transaction.
  • Subscriptions: You can sign up for subscription services like Apple Music by confirming with Face ID.
  • Existing Purchases: Face ID allows you to access previous app downloads and subscriptions.

In most cases, the Face ID prompt will activate automatically when needed. Occasionally you may need to tap the Face ID icon to trigger it manually.

Advantages of Using Face ID for App Store

Using Face ID for the App Store offers a number of benefits:

  • Convenient: It’s quicker and more convenient than entering passwords.
  • Secure: Face ID provides secure user authentication for transactions.
  • Accessibility: It allows easy access for users with disabilities.

For most users, enabling Face ID for App Store purchases and sign in streamlines the experience and enhances security.

Limitations of Using Face ID

While Face ID makes using the App Store more convenient, there are some limitations to consider:

  • Face ID only works on iPhone and iPad models with a TrueDepth camera.
  • Children under 13 cannot use Face ID.
  • Face ID won’t work well for users with certain facial features or twins/siblings.
  • Wearing sunglasses, scarves, or masks can obstruct Face ID.
  • Facial injuries, surgery, or changes in appearance can affect Face ID accuracy.

Users impacted by these limitations can continue signing in and authenticating with their Apple ID password instead of Face ID.

Troubleshooting Face ID Issues

In some cases, you may encounter issues using Face ID for App Store downloads and purchases. Try the following troubleshooting tips:

  • Check that Face ID is enabled for iTunes & App Store in Settings.
  • Make sure your face is fully visible and that you are looking directly at the device.
  • Delete and re-enroll your Face ID by going to Settings > Face ID & Passcode.
  • Update your device software as Apple occasionally releases updates to improve Face ID.
  • Remove any accessories, cases, or screen protectors that may obstruct the TrueDepth camera.
  • Reset Face ID by entering your passcode to re-enable it if locked out.

As a last resort, you can contact Apple Support for additional troubleshooting assistance if Face ID is still not working properly for App Store.

Face ID Best Practices

Follow these tips to get the best experience using Face ID:

  • Position your face directly in front of your device at a natural distance.
  • Enable attention detection to prevent unauthorized access.
  • Register an alternate appearance if you wear glasses, hats, etc.
  • Keep your eyes open without sunglasses for optimal results.
  • Only register your own face and do not share devices set up with Face ID.
  • Make sure to keep your software up to date for latest improvements.

With good set up habits and optimal use conditions, Face ID provides seamless security for your App Store purchases.

Face ID Compared to Touch ID

In summary, Face ID provides more advanced facial recognition while Touch ID relies on fingerprint scanning technology. Both are secure options for unlocking your device and authorizing App Store purchases.


Face ID provides an easy and secure way to authenticate your identity when using the App Store on supported iPhone and iPad models. Simply glancing at your device allows you to seamlessly download apps, make in-app purchases, access subscriptions, and sign in to your Apple ID.

With robust anti-spoofing technology, attention detection, and highly accurate facial scans, Face ID may be a better option than Touch ID or passwords for most users. Just be sure to follow best practices and troubleshoot any issues that come up to have the best experience.

Overall, Face ID makes transactions in the App Store both simple and secure. Turning on the “iTunes & App Store” option for Face ID is recommended to streamline downloads, purchases, and account access.
