Apple’s Touch ID is a breakthrough feature that allows users to unlock their iPhones and iPads using their fingerprints. Read on to learn how to set up Touch ID on your Apple device and how to use it along with some other useful tips and information.
Compatible devices that support Touch ID include iPhone 5S, 6, 6 Plus, 6S Plus, and SE; iPad Air 2, Mini 3, Mini 4, Pro, and Pro 9.7.
What is Touch ID and how does it work?
Touch ID is a technology that combines an integrated scanner within the Home button. It does a high-resolution 500 dpi optical scan of an image by utilizing your finger or thumb. The button is made from sapphire crystal, which acts as a lens to precisely focus on your finger, allowing the sensor to read extremely fine details of your fingerprint.
How to Set Up Touch ID on Your Device
The Touch ID will be configured automatically during your device’s setup process, but you will need to have a 4-digit entry code. The code is useful for additional security validation when registering a new fingerprint. You can also configure Touch ID later by following these steps:
- Find and tap Settings > Touch ID & Passcode > Enter Your Passcode
- Tap on Add a Fingerprint
- Press one finger on the Home button and hold it down till your device vibrates. Continue to press the Home button slightly changing the angle of your finger each time.
You can register up to 5 fingerprints ensuring that if needed, a family member can unlock your device.
How to Use Touch ID to Unlock Your Device and Make App Store Purchases
You can use the Touch ID to unlock your device every time you wake it up from sleep, just press the Home button or Sleep/Wake button to wake it up, then place your finger on the Home button or keep your finger on it to unlock it. Touch ID can also be used to make App Store purchases. Make sure it is set up to work with the App Store and use your fingerprint to make your purchases.
How Safe is Touch ID?
Every fingerprint is unique, making it rare for even a small part of two separate fingerprints to match for Touch ID. According to Apple, the probability of this happening is 1 in 50,000, making it a lot better than the 1 in 10,000 odds of guessing a typical 4-digit passcode. Touch ID stores a mathematical representation of your finger, so no image, including an actual fingerprint, is stored or transmitted. Thus, Touch ID is more secure than a password or a numerical code.
How to Fix Touch ID Issues
If you’re having trouble using Touch ID, try adding a second finger, stay consistent, and use your passcode as a backup. If the issue continues, contact Apple support for further assistance.
