## 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.

```jsx Import Example theme={null}
// root import
import { useMfaWebAuthnChangeKeyNickname } from '@auth0/auth0-acul-react';

// partial import
import {
  useMfaWebAuthnChangeKeyNickname,
  // Context hooks
  useUser,
  useTenant,
  useBranding,
  useClient,
  useOrganization,
  usePrompt,
  useScreen,
  useTransaction,
  useUntrustedData,
  // Common hooks
  useCurrentScreen,
  useAuth0Themes,
  useErrors,
  // Utility hooks
  useChangeLanguage,
  // Methods
  continueWithNewNickname,
} from "@auth0/auth0-acul-react/mfa-webauthn-change-key-nickname";

function MfaWebAuthnChangeKeyNicknameScreen() {
  const { continueWithNewNickname } = useMfaWebAuthnChangeKeyNickname();
  return (
    <button onClick={() => continueWithNewNickname({ nickname: 'My Security Key' })}>
      Save Nickname
    </button>
  );
}
```
