MfaCountryCodes - Auth0 Docs

The mfa-country-codes screen allows users to browse and select a country code for phone-based MFA enrollment or challenge flows.

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, which is useful when you want a unified build to handle all possible screens.

Import Example

// root import
import { useMfaCountryCodes } from '@auth0/auth0-acul-react';

// partial import
import {
  useMfaCountryCodes,
  // Context hooks
  useUser,
  useTenant,
  useBranding,
  useClient,
  useOrganization,
  usePrompt,
  useScreen,
  useTransaction,
  useUntrustedData,
  // Common hooks
  useCurrentScreen,
  useAuth0Themes,
  useErrors,
  // Utility hooks
  useChangeLanguage,
  // Methods
  goBack,
  selectCountryCode,
} from "@auth0/auth0-acul-react/mfa-country-codes";

function MfaCountryCodesScreen() {
  const { selectCountryCode } = useMfaCountryCodes();
  return (
    <button onClick={() => selectCountryCode({ country_code: 'US', phone_prefix: '+1' })}>
      Select +1 (US)
    </button>
  );
}
