react-native-biopass-updated v1.0.0-alpha.2

react-native-biopass-updated

Store a password behind biometric authentication.

Currently only supports the Android platform.

This package uses androidx.biometric.BiometricPrompt with fallback to android.hardware.fingerprint.FingerprintManager for Android versions below Android P and can only be used in projects using googles androidx library. RN versions above 0.60 use androidx library by default.

With this I have also implemented device passcode fallback support in case of biometric authentication failure. While its easy to implement passcode fallback for BiometricPrompt its a bit tricky for FingerPrintManager and you will have to update the MainActivity.java of your application to do this. Follow the steps below in #MainActivity in ## Usage to do this.

Installation

npm install --save react-native-biopass-updated
react-native link react-native-biopass-updated

Usage

import BioPass from 'react-native-biopass-updated'

// Store a password for future retreival
BioPass.store("secret", password)
  .then(() => console.log(`Password stored!`))
  .catch((err) => console.log(`Failed to store password: ${err}`)

// Retreive a stored password (will trigger Fingerprint / TouchID / FaceID prompt)
BioPass.retreive("Give us the secret password!")
  .then((password) => console.log(`The password was: ${password}`))
  .catch((err) => console.log(`Failed to retreive password: ${err}`)

// Delete the stored password
BioPass.delete()
  .then(() => console.log(`Password deleted!`))
  .catch((err) => console.log(`Failed to delete password: ${err}`)

MainActivity

import android.app.Activity; import com.reactlibrary.RNBioPassPackage; import com.facebook.react.common.LifecycleState; import com.facebook.react.ReactRootView; import com.facebook.react.ReactInstanceManager;

public class MainActivity extends AppCompatActivity {

private ReactInstanceManager mReactInstanceManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //Instantiate ReactInstanceManager
    this.mReactInstanceManager = ReactInstanceManager.builder()
            .setApplication(getApplication())
            .setCurrentActivity(this)
            .setBundleAssetName("index.android.bundle")
            .addPackage(new RNBioPassPackage())
            .setUseDeveloperSupport(BuildConfig.DEBUG)
            .setInitialLifecycleState(LifecycleState.RESUMED)
            .build();
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Activity activity = this;
    mReactInstanceManager.onActivityResult(activity, requestCode, resultCode, data);
}

}
