You can use `useAuthenticator` hook to access functions that lets you trigger transitions to the authenticator. Please see [Full API](#full-api) to see all supported transition functions. Any invalid transitions (e.g. `signUp` directly to `authenticated`) will be ignored.

```jsx
import { Button } from 'react-native';
import { useAuthenticator } from '@aws-amplify/ui-react-native';

const Home = () => {
  const { user, signOut } = useAuthenticator((context) => [context.user]);

  return <Button onPress={signOut} title={`Welcome, ${user.username}!`} />;
};
```
