The mfa-webauthn-platform-challenge screen prompts the user to complete an MFA challenge using a platform authenticator, such as Touch ID or Windows Hello, built into their device.

​
Import

Each screen has its own set of hooks and methods. The SDK supports partial import and root import for each screen.
  • Using partial import allows you include only the code you need for your specific use case.
  • Using root import allows you to load all screens from a single bundle useful when you want a unified build to handle all possible screens.
Import Example
// root import
import { useMfaWebAuthnPlatformChallenge } from '@auth0/auth0-acul-react';

// partial import
import {
  useMfaWebAuthnPlatformChallenge,
  // Context hooks
  useUser,
  useTenant,
  useBranding,
  useClient,
  useOrganization,
  usePrompt,
  useScreen,
  useTransaction,
  useUntrustedData,
  // Common hooks
  useCurrentScreen,
  useAuth0Themes,
  useErrors,
  // Utility hooks
  useChangeLanguage,
  // Methods
  reportBrowserError,
  tryAnotherMethod,
  verify,
} from "@auth0/auth0-acul-react/mfa-webauthn-platform-challenge";

function MfaWebAuthnPlatformChallengeScreen() {
  const { verify } = useMfaWebAuthnPlatformChallenge();
  return (
    <button onClick={() => verify({ rememberDevice: true })}>
      Verify with Platform Authenticator
    </button>
  );
}
