BiometricUserVerifier class abstract

The object in charge of interacting with the user to do biometric authentication.

It is invoked when the operation uses the biometric (Aaid.biometric) authenticator.

The SDK does not provide implementations of this interface. The implementation must be done by the user of the SDK if the biometric authenticator is required.

Notes \

  • Android: invoked for the Biometric authenticator (BiometricPrompt-based).
  • iOS: invoked for the Face ID authenticator. For Touch ID, see FingerprintUserVerifier.
