The 2FA Verification resource provides the ability to retrigger a 2FA email for Authentication+ association with the [BrandRegistration resource](/docs/messaging/api/brand-registration-resource).

The 2FA Verification resource is a subresource of the BrandRegistration resource.

## Base URL

All URLs referenced in the API documentation have the following base:

`https://messaging.twilio.com/v1/a2p/BrandRegistrations`

## Create a 2FA Verification resource

**Resource URL**: `https://messaging.twilio.com/v1/a2p/BrandRegistrations/{BrandSid}/2fa`

To initiate a 2FA Verification for the Brand, make a `POST` request to this resource.

See the following code sample for a complete curl request.

```bash
curl --location --request POST 'https://messaging.twilio.com/v1/a2p/BrandRegistrations/BNXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX/2fa' \
-u "Account_SID:Auth_Token" \
--header 'Content-Type: application/json' \
```

> \[!WARNING]
>
> Don't create a [UsAppToPerson resource](/docs/messaging/api/usapptoperson-resource) until the Brandregistration resource's `vetting_status` is `FAILED`.
>
> You can check the `vetting_status` through fetching the BrandVetting resource.
>
> Once the BrandVetting status is `FAILED` and the 2FA Verification is initiated, a new email will be sent and this will incur a new Authentication+ fee.
