Shaved my beard now Face ID won’t work

Re: "Shaved my beard now Face ID won’t work:

I need to use my Face ID to chance my Face ID. How can I sort this out?"

Apple Support's article: Set up Face ID on iPhone - Apple Support

says you can:

"Use Face ID while wearing a face mask". ... if you have that set-up already ... try that!

Else: If you want to check whether you can still set it up at the moment:

article says: "On iPhone 12 models, iPhone 13 models, iPhone 14 models, iPhone 15 models, and iPhone 16 models, you can use Face ID to unlock your phone while you wear a face mask (or other covering that blocks your mouth and nose).

When you turn on Face ID with a Mask, Face ID analyzes the unique characteristics around your eyes, and it works with all of the Face ID options you turn on in Settings > Face ID & Passcode.

Note: Face ID is most accurate when it’s set up for full-face recognition only.

Go to Settings > Face ID & Passcode, then do any of the following:

• Allow Face ID to work while you wear a face mask: Turn on Face ID with a Mask, then follow the onscreen instructions.
• Important: If you usually wear glasses, you can improve the accuracy of Face ID by wearing a pair of transparent glasses (not sunglasses) when you turn on Face ID with a Mask.
• Add a pair of transparent glasses (not sunglasses) to your appearance: Tap Add Glasses, then follow the onscreen instructions.
• Don’t allow Face ID to work while you wear a face mask: Turn off Face ID with a Mask."
