open suspend override fun authenticate(parameters: Biometrics.AuthenticateParameters): BiometricsAuthResponse

open override fun authenticate(parameters: Biometrics.AuthenticateParameters, callback: (BiometricsAuthResponse) -> Unit)

Indicates if there is an existing biometric registration on device.

open override fun register(parameters: Biometrics.RegisterParameters, callback: (BiometricsAuthResponse) -> Unit)

When a valid/active session exists, this method will add a biometric registration for the current user. The user will later be able to start a new session with biometrics or use biometrics as an additional authentication factor.
