Face ID has been the default security feature for Apple’s smartphones since its debut. However, if you would like to share your iPhone with a partner, friend, or child, unlocking might be a little difficult. Fortunately, just like Touch ID allows you to save multiple fingerprints, there is a way to enable another person’s face to unlock your iPhone. Let’s explore how to add another Face ID.

  • Set up an Alternate Appearance for Face ID to allow other family members or friends to unlock your device in case of emergency.
  • If someone is sharing an iPhone, adding two appearances to Face ID ensures both users can get into the phone.

This tip was performed on an iPhone 14 Pro running iOS 18.4.1.

Before we begin, it’s essential to note that the Alternate Appearance option is designed to enable the use of Face ID and Apple Pay while wearing glasses, sunglasses, facemasks, hats, and other similar accessories.

Please be aware that if you set up this feature to add the face of a partner, friend, or child so that they can unlock your phone, they will have full access to your device.

Now, here’s how to add a second Face ID by adding an alternate appearance.

First, open the Settings app, and select Face ID & Passcode option. You will be prompted to enter your passcode to continue. Refer to the image below:

Selecting the Face ID & Passcode option

Next, tap Set Up an Alternate Appearance option. See the image below:

Selecting the Setup Up an Alternate Appearance option

Now, tap Get Started and follow the on-screen prompts to add a second face to Face ID. See the following image:

Selecting Get Started, then Done when finished

Next, if you do not see the Set Up an Alternate Appearance button, you may already have an alternate appearance saved. The only way to remove an alternate appearance and add a new one is to tap Reset Face ID. When resetting Face ID, you will need to set up your own face again before setting up the alternate appearance. Refer to the image below:

Selecting the Reset Face ID option

That’s how to add another face to Face ID. Once you have set up an Alternate Appearance for Face ID, they should have no problem using Face ID to unlock your device. This can be incredibly useful in the event of an emergency in which you are unable to unlock your phone yourself.

Be aware that if you have locked any apps with Face ID, any other faces you have saved as alternate appearances will also be able to unlock them. Alternate faces will also be able to make purchases with Face ID.

Additionally, you can setup an Alternate Appearance when wearing a mask. First, head to:

Settings > Face IO & Passcode

You will be prompted to enter your passcode to continue. See the image below:

Selecting the Face ID & Passcode option

Next, scroll down and tap Setup Face ID with a Mask for Alternate Appearance. See the following image:

Now, tap Use Face ID with a Mask and follow the on-screen prompts. Refer to the image below:

Secure Your iPhone: Lock Apps with Face ID

With recent iOS updates, iPhone users can now lock apps, enhancing privacy and security. To lock an app, long-press the icon and select “Require Face ID.” If Face ID fails, users can unlock via passcode. However, certain apps like Maps and Clock cannot be locked.

Can you lock apps on the iPhone? Yes! For a long time, there was no way to lock apps on iOS. However, the latest updates added a new feature that allows you to lock down an app.

This is useful because it means you can unlock your iPhone and hand it to someone to look at something, knowing they will not be able to open the locked apps. Suppose someone using your iPhone tries to open an app you have manually locked using the method described below. In that case, they will see a popup informing them that it can not be accessed without secondary authentication via Face ID (or Touch ID on the iPhone SE). 

If Stolen Device Protection is active, entering a passcode to unlock an app is not an option, so even if your iPhone is stolen and the thief knows your passcode, they can open the app. However, if Stolen Device Protection is not enabled, a passcode prompt appears that can be used to unlock the app after three failed Face ID attempts.

It’s worth noting that not all apps can be locked. Apple does not provide the lock option for apps like Maps, Clock, Calculator, and Settings. Otherwise, almost every other app can be locked, including third-party apps. Let’s explore how this is done.

  • Prevent others from accessing apps with personal information.
  • Secure apps that do not have a Face ID login option.

This is for the iPhone running iOS 18 or later. The screenshots are from iPhone 14 Pro running iOS 18.2.1.

First, find the app you want to lock, and long-press on it. Refer to the below page:

Lock App 1
Find an app you want to lock

Next, when the menu appears, select Require Face ID. See the below image:

Lock App 2
Select the Require Face ID option

Now, tap Require Face ID. See the following image:

Lock App 3
Tap the Require Face ID option

Next, Face ID will scan your face. When you open the app, there will be a message telling you that Face ID is required to open the app. Refer to the below image:

Lock App 4
Point your iPhone at your face to open the locked app

Now, you can tap Try Face ID Again if Face ID fails. See the below image:

Lock App 5
If the Face ID scan fails then tap and try again

Next, if Face ID fails a second time, you can select Enter Passcode to unlock the app with your iPhone passcode. See the following image:

Lock App 6
If Face ID fails again then enter your passcode to open the locked app

Simply long-press on the app’s icon and choose the Don’t Require Face ID. See the below image:

Lock App 7
Remove the requirement to use Face ID for the app

As long as you have Stolen Device Protection enabled, turning the lock on and off requires a ‌Face ID‌ scan, so it can not be turned off without your knowledge.

That’s how to lock an app on the iPhone. Now you can keep your apps protected from prying eyes.
