  An array of [Identifier](/docs/libraries/acul/react-sdk/API-Reference/Types/interfaces/Identifier) objects, where each contains a `type` (identifier type)
  and a `required` flag indicating whether it is mandatory for signup.

  ```tsx Example theme={null}
  import { useSignupIdentifiers } from '@auth0/auth0-acul-react/signup';

  const identifiers = useSignupIdentifiers();
  const emailIdentifier = identifiers.find(({ type }) => type === 'email');
  const phoneIdentifier = identifiers.find(({ type }) => type === 'phone');
  const usernameIdentifier = identifiers.find(({ type }) => type === 'username');

  const emailRequired = emailIdentifier?.required ?? false;
  const phoneRequired = phoneIdentifier?.required ?? false;
  const usernameRequired = usernameIdentifier?.required ?? false;
