Authenticating via touch ID or fingerprint sensor

Security is a paramount concern in software, especially when there is any sort of authentication. Breaches and leaked passwords have become a part of the daily news cycle, and companies of all sizes are wising up to the need for implementing added security measures in their apps. One such measure in mobile devices is biometric authentication, which uses fingerprint scanning or face recognition technology to provide supplementary identification methods.

This recipe covers how to add fingerprint scanning and face recognition security. Thanks to the react-native-touch-id library, this process has been simplified and streamlined in React Native app development.
