The signup screen collects the user’s credentials to create a new account. It supports standard signup with username, email, phone number, and password, as well as federated signup via social or enterprise connections.
Signup

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

// partial import
import {
  useSignup,
  // Context hooks
  useUser,
  useTenant,
  useBranding,
  useClient,
  useOrganization,
  usePrompt,
  useScreen,
  useTransaction,
  useUntrustedData,
  // Common hooks
  useCurrentScreen,
  useAuth0Themes,
  useErrors,
  // Utility hooks
  useChangeLanguage,
  usePasswordValidation,
  useSignupIdentifiers,
  useUsernameValidation,
  // Methods
  signup,
  federatedSignup,
  pickCountryCode,
} from '@auth0/auth0-acul-react/signup';

function SignupForm() {
  const { signup } = useSignup();
  return (
    <button onClick={() => signup({ email: 'user@example.com', password: 'secret' })}>
      Create Account
    </button>
  );
}
