# 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

```
try {
  await Web3AuthFlutter.enableMFA();
} on UserCancelledException {
  log("User cancelled.");
} catch(e) {
  log("Unknown exception occurred");
}

```

Usage

```
try {
    final loginParams = LoginParams(
        loginProvider: Provider.jwt,
        extraLoginOptions: ExtraLoginOptions(
            id_token: "YOUR_JWT_TOKEN",
        ),
    );

    await Web3AuthFlutter.enableMFA(loginParams);
} on UserCancelledException {
  log("User cancelled.");
} catch(e) {
  log("Unknown exception occurred");
}

```
