Where is the Touch ID sensor?
The Touch ID sensor is either in the Home button or—on iPad Air (4th generation)—the top button. When you follow the steps below, the onscreen instructions will tell you which button to use.
Safari 14 will let you use Face ID or Touch ID to log in to websites. The functionality is built on the WebAuthn component of the FIDO2 standard, and it allows for easier and more secure logins. Oct 22, 2020 Make sure that the Touch ID sensor and your finger are clean and dry. Tap Settings Touch ID & Passcode, then enter your passcode. Tap Add a Fingerprint and hold your device as you normally would when touching the Touch ID sensor. Touch the Touch ID sensor with your finger—but don't press.
Follow these steps. Try using Touch ID after each step:
- Make sure that you have the latest version of iOS or iPadOS.
- Make sure that your fingers and the Touch ID sensor are clean and dry.* For the Touch ID sensor, use a clean, lint-free cloth to wipe off any dirt or debris.
- Your finger should cover the Touch ID sensor completely, touching the surrounding metal ring. While Touch ID is scanning, you shouldn't tap too quickly or move your finger around.
- If you're using a case or screen protector, make sure it doesn't cover the Touch ID sensor or the surrounding ring.
- Go to Settings > Touch ID & Passcode and make sure that iPhone Unlock or iTunes & App Store is on, and that you've enrolled one or more fingerprints.
- Try enrolling a different finger.
