How can I use it in an Activity #1

Thanks for your excellent work for this lib. 👍👍

But why the BiometricHelper has to be instanced in a fragment? How can I use it in an activity?

class BiometricHelper(private val fragment: Fragment)

Isn't this a better way?

class BiometricHelper(private val context: Context)

Hello, Sorry this is not possible due to the implementation of Google of BiometricPrompt. You absolutely need a Fragment or a FragmentActivity: https://developer.android.com/reference/androidx/biometric/BiometricPrompt#BiometricPrompt(androidx.fragment.app.FragmentActivity,%20java.util.concurrent.Executor,%20androidx.biometric.BiometricPrompt.AuthenticationCallback)
