OutOfBandRegistration

public protocol OutOfBandRegistration : HttpOperation

The operation handling an out-of-band registration. This is the object returned by the SDK, when an OutOfBandPayload was processed and the OutOfBandPayload corresponds to a registration operation.

Usage example:

class AuthenticatorSelectorImpl: AuthenticatorSelector {
    func selectAuthenticator(context: AuthenticatorSelectionContext, handler: AuthenticatorSelectionHandler) {
        handler.aaid(aaid)
    }
}

class BiometricUserVerifierImpl: BiometricUserVerifier {
    func verifyBiometric(context: BiometricUserVerificationContext, handler: BiometricUserVerificationHandler) {
        handler.verify()
    }
}

class DevicePasscodeUserVerifierImpl: DevicePasscodeUserVerifier {
    func verifyDevicePasscode(context: DevicePasscodeUserVerificationContext, handler: DevicePasscodeUserVerificationHandler) {
        handler.verify()
    }
}

class PinEnrollerImpl: PinEnroller {
    func enrollPin(context: PinEnrollmentContext, handler: PinEnrollmentHandler) {
        handler.pin(pin)
    }
}

class PasswordEnrollerImpl: PasswordEnroller {
    func enrollPassword(context: PasswordEnrollmentContext, handler: PasswordEnrollmentHandler) {
        handler.password(password)
    }
}

            .deviceInformation(.init(name: "<name>", fcmRegistrationToken: "<target>"))
            .authenticatorSelector(AuthenticatorSelectorImpl(...))
            .biometricUserVerifier(BiometricUserVerifierImpl(...))
            .devicePasscodeUserVerifier(DevicePasscodeUserVerifierImpl(...))
            .pinEnroller(PinEnrollerImpl(...))
            .passwordEnroller(PasswordEnrollerImpl(...))
            .onError { error in
                ...
            }
            .onSuccess {
                ...
            }
            .execute()
    }
    .onAuthentication { oobAuthentication in
        ...
    }
    .execute()

The biometric and device Passcode authenticators are enrolled at the OS level. That is why, if one of them must be registered, the user must authenticate through BiometricUserVerifier or DevicePasscodeUserVerifier. In the case of the PIN and password, the credentials are enrolled during registration, so no verification is needed.
