Use Touch ID (supported models) to securely and conveniently unlock iPhone, authorize purchases and payments, and sign in to many third-party apps with your finger or thumb on the Home button.
You can choose when to use Touch ID, add a fingerprint, name or delete a fingerprint, or turn off Touch ID. You can add more than one fingerprint, too, such as both of your thumbs and forefingers.
Here’s how to set up Touch ID on iPhone.
To use Touch ID, you must also set up a passcode on your iPhone.
Turn on Touch ID
- Open Settings and then tap Touch ID & Passcode.
- Turn on any of the options below Use Touch ID For. Then follow the onscreen instructions.
With iTunes & App Store turned on, you’re asked for your Apple Account password the first time you buy something from the App Store, Apple Books, or the iTunes Store. After that, you’re asked to use Touch ID for your purchases.
