Touch ID and Face ID overview
Passcodes and password are critical to the security of Apple devices, but users need to be able to quickly access their devices—even upwards of a hundred times a day. Biometric authentication provides an opportunity to retain the security of a strong passcode—or even to strengthen the passcode or password since it won’t often need to be entered manually—while providing the convenience of swiftly unlocking with a finger press or glance. Touch ID and Face ID don’t replace the password or passcode, but they do make access faster and easier in most situations.
