# MfaPhoneChallenge
> Describes all the hooks and methods available to customize the Universal Login `mfa-phone-challenge` screen.
The `mfa-phone-challenge` screen prompts the user to verify their identity by entering a code sent to their phone via SMS or voice call.
## 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 { useMfaPhoneChallenge } from '@auth0/auth0-acul-react';
// partial import
import {
useMfaPhoneChallenge,
// Context hooks
useUser,
useTenant,
useBranding,
useClient,
useOrganization,
usePrompt,
useScreen,
useTransaction,
useUntrustedData,
// Common hooks
useCurrentScreen,
useAuth0Themes,
useErrors,
// Utility hooks
useChangeLanguage,
// Methods
continueMethod,
pickPhone,
tryAnotherMethod,
