Examples

ngCordova Example

Ionic Native Example

Install from NPM

cordova plugin add cordova-plugin-fingerprint-aio --save

If you want to set a FaceID description use:

cordova plugin add cordova-plugin-fingerprint-aio --variable FACEID_USAGE_DESCRIPTION="Login now...."

Use the release candidate for testing the latest fixes

You can use preview versions with the rc tag on npm.

cordova plugin add cordova-plugin-fingerprint-aio@rc

Use this Github repo

Get the latest development version. Not recommended!

cordova plugin add https://github.com/NiklasMerz/cordova-plugin-fingerprint-aio.git

Fingerprint.isAvailable(isAvailableSuccess, isAvailableError);

    function isAvailableSuccess(result) {
      /*
      result depends on device and os. 
      iPhone X will return 'face' other Android or iOS devices will return 'finger'  
      */
      alert("Fingerprint available");
    }

    function isAvailableError(error) {
      // 'error' will be an object with an error code and message
      alert(error.message);
    }

Fingerprint.show({
      description: "Some biometric description"
    }, successCallback, errorCallback);

    function successCallback(){
      alert("Authentication successful");
    }

    function errorCallback(error){
      alert("Authentication invalid " + error.message);
    }

• title: Title in authentication dialogue. Default: "<APP_NAME> Biometric Sign On"
• subtitle: Subtitle in authentication dialogue. Default: null
• description: Description in authentication dialogue. Defaults:
  • iOS: "Authenticate" (iOS' evaluatePolicy() requires this field)
  • Android: null
• fallbackButtonTitle: Title of fallback button. Defaults:
  • When disableBackup is true
    • "Cancel"
  • When disableBackup is false
    • iOS: "Use PIN"
    • Android: "Use Backup" (Because backup could be anything pin/pattern/password ..haven't figured out a reliable way to determine lock type yet source)
• disableBackup: If true remove backup option on authentication dialogue. Default: false. This is useful if you want to implement your own fallback.

Thanks to the authors of the original fingerprint plugins

Some code is refactored from their projects and I learned how to make Cordova plugins from their great plugins:

@EddyVerbruggen and @mjwheatley

Android

iOS

Starting with version 3.0.0 the iOS and Android parts are written from scratch.

Special thanks also to @anitaa1990 for the biometric lib that aar the file in this plugin is based on and to @pabloerag's fork that removed the androidx requirements.
