FingerprintUserVerifier class abstract

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

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

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

Notes \

  • Android: invoked for the legacy Fingerprint authenticator.
  • iOS: invoked for the Touch ID authenticator. For Face ID, see BiometricUserVerifier.
