• Biometric library version: 1.2.0-alpha03

Code:

try {
    activity.authenticateWithClass2BiometricsOrCredentials(
        title = activity.getString(R.string.biometric_title),
        subtitle = activity.getString(R.string.biometric_subtitle),
        confirmationRequired = false
    )
} catch(e: Exception){
    // Do something
}

STEPS TO REPRODUCE [Be as specific as possible please]

1. Start authentication
2. Try wrong finger for authentication so that AuthPromptFailureException() gets thrown

OBSERVED RESULTS
