# Enable MFA

Call `enableMFA` with the user's `LoginParams` to start the multi-factor authentication (MFA) setup flow. For custom authentication, include the connection ID and identity token.

tip

Additionally you can associate a function to be triggered on successful MFA Enabled.

```
void Start()
{
    web3Auth = GetComponent<Web3Auth>();
    web3Auth.setOptions(new Web3AuthOptions()
    {

    });
    web3Auth.onMFASetup += onMFASetup;
}
private void onMFASetup(bool response)
{
    // Functions to be called after MFA setup
}

```

public void enableMFA()
