How to Set Up Touch ID on iPhone?

Quick Answer

Open Settings > Touch ID & Passcode, enter your passcode, then tap Add a Fingerprint and follow the prompts.

Before You Start

• Touch ID is available on iPhone models with a Home button or a Touch ID power button (model-dependent).
• Make sure your finger and the Touch ID sensor are clean and dry.

Step-by-Step: Add a Fingerprint

1. Settings > Touch ID & Passcode.
2. Enter your current passcode.
3. Tap Add a Fingerprint.
4. Rest your finger on the sensor repeatedly as instructed.
5. Adjust your grip to capture edge areas.
6. Name the fingerprint (e.g., Right Thumb).

Troubleshooting Touch ID

• If it’s inconsistent, add the same finger twice (two fingerprints for one finger).
• Remove old prints: Touch ID & Passcode > tap a fingerprint > Delete Fingerprint.
• If it stops working, restart and update iOS; check for a damaged Home button/sensor.
