# Manage MFA settings

The `manageMFA` method opens a browser where the user can add, remove, and configure their MFA factors from the templated user interface.

The method takes optional `LoginParams`, the same as [enableMFA](/embedded-wallets/sdk/flutter/usage/enable-mfa/). It returns a `bool` that indicates whether the flow completed. It throws if the user hasn't enabled MFA yet (`MFA_NOT_ENABLED` on Android, `mfaNotEnabled` on iOS).

Not available for `idToken` sessions

In v8, `enableMFA` and `manageMFA` throw when the current session was created with `idToken`(custom JWT sign-in such as Firebase), or when you pass `LoginParams` with `idToken`. On Android the error is `ENABLE_MFA_NOT_ALLOWED`; on iOS it's `enabledMfaNotAllowed`. Users who signed in with an OAuth flow, including custom connections configured with `authConnectionConfig` and `ExtraLoginOptions`, can use MFA.

## Usage

```dart
try {
  final bool result = await Web3AuthFlutter.manageMFA();
} on PlatformException catch (e) {
  log(e.message ?? e.toString());
}

```
