To add a fingerprint (Touch ID) on your iPhone, you'll need to access the Settings app. Here's how:
- Open the Settings app on your iPhone.
- Scroll down and tap on Touch ID & Passcode (or Face ID & Passcode on newer iPhones without a Home button).
- Enter your passcode.
- Tap on Add a Fingerprint.
- Follow the on-screen instructions to scan your fingerprint multiple times from various angles. The iPhone will guide you through placing and lifting your finger on the Touch ID sensor (or guiding you through Face ID setup if your phone uses facial recognition).
- Once the scan is complete, you can name the fingerprint for easy identification (e.g., "Right Thumb").
- You can add more fingerprints by repeating steps 4-6.
