# Enable MFA for a user

The `enableMFA` method is used to trigger MFA setup flow for users. The method takes `LoginParams` which will used during custom verifiers. If you are using default login providers, you don't need to pass `LoginParams`. If you are using custom JWT verifiers, you need to pass the JWT token in `loginParams` as well.

## Usage[​](#usage "Direct link to Usage")

- Default Verifier
- Custom JWT Verifier

Usage

```
import android.widget.Button
import com.web3auth.core.Web3Auth
import android.os.Bundle

class MainActivity : AppCompatActivity() {
    private lateinit var web3Auth: Web3Auth

     private fun enableMFA() {
       val completableFuture = web3Auth.enableMFA()

        completableFuture.whenComplete{_, error ->
            if (error == null) {
                Log.d("MainActivity_Web3Auth", "Launched successfully")
                // Add your logic
            } else {
                // Add your logic on error
                Log.d("MainActivity_Web3Auth", error.message ?: "Something went wrong")
            }
        }
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        ...
        // Setup UI and event handlers
        val enableMFAButton = findViewById<Button>(R.id.enableMFAButton)
        enableMFAButton.setOnClickListener { enableMFA() }
        ...
    }
    ...
}
