Mob.Biometric (mob v0.3.5)

Biometric authentication (Face ID / Touch ID / fingerprint).

No permission dialog is shown — uses the device's existing biometric enrollment.

Mob.Biometric.authenticate(socket, reason: "Confirm payment")

Result arrives as:

handle_info({:biometric, :success},       socket)
handle_info({:biometric, :failure},        socket)
handle_info({:biometric, :not_available},  socket)

:not_available is returned if the device has no biometric hardware or the user has not enrolled any biometrics.
