Android Fingerprint Auth
$ ionic cordova plugin add cordova-plugin-android-fingerprint-auth $ npm install @ionic-native/android-fingerprint-auth
Plugin Repo: https://github.com/mjwheatley/cordova-plugin-android-fingerprint-auth
This plugin will open a native dialog fragment prompting the user to authenticate using their fingerprint. If the device has a secure lockscreen (pattern, PIN, or password), the user may opt to authenticate using that method as a backup.
