Users benefit from the biometric security feature Face ID and Touch ID because these characteristics let them fast unlock their devices. Besides normal operation there are three main causes that could disable your Face ID or Touch ID security mechanism: software bugs, hardware concerns, or improper configuration. This document provides you with information to resolve Face ID and Touch ID malfunctioning on laptops as well as smartphones.
Common Reasons Why Face ID or Touch ID Might Not Work
- The function of fingerprint scanners or Face ID sensors will be compromised by any form of grime accumulation or materials blocking their surface.
