# Enable MFA for a user

> Web3Auth Android SDK - enableMFA Function | Embedded Wallets

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.
