Touch ID


Touch ID is the Digital Identity presented from Apple's fingerprint scanner on iPhone 5S (and we assume later) devices.

Touch ID is an Authentication Method which uses a Biometric Sample from the Fingerprint which is a Physiological Characteristic of a Digital Identity and used for Authentication and can be defined a Something You Are in Multi-Factor Authentication.

Only a few other smartphone makers have built fingerprint scanning into their phones, as with the Motorola Mobility Atrix 4G in 2011 and several of the Samsung devices. The iPhone 5S is the first phone on a major US carrier since then to feature the technology.

In 2012, Apple acquired AuthenTec, a company focused on fingerprint reading and identification management software, for $356 million. Since then, people have expected a fingerprint reading feature.

To configure Touch ID#

You must first set up a passcode. Touch ID is designed to minimize the input of your passcode; but your passcode will be needed for additional security validation:
  • After restarting your device
  • When more than 48 hours have elapsed from the last time you unlocked your device
  • To enter the Touch ID & Passcode setting

Touch ID's hardware is manufactured by AuthenTec which was acquired by Apple Inc On 27 July 2012 for $356 million[2]
