The email-identifier-challenge screen is displayed when a user needs to verify their identity by entering a code sent to their email address. It allows the user to submit the code, resend it, or return to the previous step.
ACUL Email Identifier Challenge

​
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 to 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 { useEmailIdentifierChallenge } from '@auth0/auth0-acul-react';

// partial import
import {
  useEmailIdentifierChallenge,
  // Context hooks
  useUser,
  useTenant,
  useBranding,
  useClient,
  useOrganization,
  usePrompt,
  useScreen,
  useTransaction,
  useUntrustedData,
  // Common hooks
  useCurrentScreen,
  useAuth0Themes,
  useErrors,
  useResend,
  // Utility hooks
  useChangeLanguage,
  // Methods
  submitEmailChallenge,
  resendCode,
  returnToPrevious,
} from '@auth0/auth0-acul-react/email-identifier-challenge';

function EmailIdentifierChallengeScreen() {
  const { submitEmailChallenge } = useEmailIdentifierChallenge();
  return (
    <button onClick={() => submitEmailChallenge({ code: '123456' })}>Submit</button>
  );
}
