Using Face ID or Touch ID on your iPhone allows you to quickly and securely unlock your device, make purchases with Apple Pay, and access password-protected apps and features. Here’s how to use Face ID or Touch ID:

Using Face ID (Available on iPhone X and later models)

1. Set Up Face ID:

   • During the initial setup of your iPhone, you’ll be prompted to set up Face ID. Follow the on-screen instructions to scan your face from different angles.

2. Unlock Your iPhone:

   • To unlock your iPhone using Face ID, simply raise your iPhone to wake it, then look at the TrueDepth camera at the top of the screen. If Face ID recognizes you, the lock icon will animate, and your iPhone will unlock.

3. Confirm Using Face ID for Purchases:

   • Face ID can be used to authorize purchases with Apple Pay and in the App Store. Simply double-click the side button (on iPhone models with Face ID) or tap the side button (on iPhone models without Face ID) and look at your iPhone to authenticate.

4. Use Face ID for Password Autofill:

   • Face ID can autofill passwords in apps and Safari. When prompted to enter a password, Face ID will authenticate you, and you can choose to autofill the password stored in your iCloud Keychain.

Using Touch ID (Available on iPhone 5s through iPhone 8 and some iPad models)

1. Set Up Touch ID:

   • During the initial setup of your iPhone, you’ll be prompted to set up Touch ID. Follow the on-screen instructions to scan your fingerprint.

2. Unlock Your iPhone:

   • To unlock your iPhone using Touch ID, gently rest your finger or thumb on the Home button (for iPhone models with Touch ID) or the Power button (for iPad models with Touch ID). If Touch ID recognizes your fingerprint, your iPhone will unlock.

3. Confirm Using Touch ID for Purchases:

   • Touch ID can be used to authorize purchases with Apple Pay and in the App Store. Simply rest your finger or thumb on the Home button (or Power button on iPad) to authenticate.

4. Use Touch ID for Password Autofill:

   • Touch ID can autofill passwords in apps and Safari. When prompted to enter a password, Touch ID will authenticate you, and you can choose to autofill the password stored in your iCloud Keychain.

Additional Tips

• Improve Recognition: If Face ID or Touch ID isn’t recognizing you consistently, you can improve recognition by rescanning your face or fingerprints in the Face ID & Passcode or Touch ID & Passcode settings.

• Accessibility: Face ID and Touch ID have accessibility features to accommodate different users’ needs, such as alternative appearance for Face ID and alternative fingerprint recognition for Touch ID.

• Security: Face ID and Touch ID data is securely stored on your device and never transmitted to Apple servers or backed up to iCloud.

By following these steps and tips, you can easily use Face ID or Touch ID to unlock your iPhone, authorize purchases, and access password-protected features with ease and security.
