How to Set Up Face ID on iPhone

After the Home button was removed from iPhone X and above, Face ID became the primary and fastest method to unlock iPhones. Apart from unlocking, it’s also used to make payments with Apple Pay and sign into apps and websites.

Face ID is a powerful feature that can recognize your face even when it’s dark. With the introduction of iOS 15.4 (and for iPhone 12 models and above), you can use Face ID even when wearing a mask.

The following iPhone models support Face ID: iPhone X, 11, 12, 13, and their variants.
