Remarks
A class that coordinates access to the fingerprint hardware.
This member is deprecated. See BiometricPrompt which shows a system-provided dialog upon starting authentication. In a world where devices may have different types of biometric authentication, it's much more realistic to have a system-provided authentication dialog since the method may vary by vendor/device.
