# useEnableMFA

Hook to enable Multi-Factor Authentication (MFA) for the current user's embedded wallet.

info

This hook only works for social login embedded wallets. It is not available for external wallet connections.

### Import

```tsx
import { useEnableMFA } from '@web3auth/react-native-sdk'

```

### Usage

```tsx
import { useEnableMFA } from '@web3auth/react-native-sdk'

function EnableMFAButton() {
  const { enableMFA, loading, error } = useEnableMFA()

  return (
    <View>
      <Button
        title={loading ? 'Setting up MFA…' : 'Enable MFA'}
        disabled={loading}
        onPress={() => enableMFA()}
      />
      {error && <Text>{error.message}</Text>}
    </View>
  )
}

```

### Return type

#### `enableMFA`

`() => Promise<void>`

#### `loading`

`boolean`

`true` while the MFA setup process is in progress.

#### `error`

`Web3AuthError | null`

Error from the most recent `enableMFA` call, or `null` if successful.
