If you haven't set it up, Go to Settings > Touch ID & Passcode and follow the prompts there.
If it won't unlock or set up-
- 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.
- Try enrolling a different finger.
If you can't turn on Touch ID, Touch ID is dimmed or grayed out, and/or you see "Failed—unable to complete Touch ID setup", you'll have to take your device to an Apple Retail Store or Apple Authorized Service Provider, or contact Apple Support.
