# Set up multifactor authentication

Verify your identity when you sign in to Merchant Home.

Multifactor authentication (MFA), also called two-factor authentication (2FA), helps protect your Merchant Home account.

### Verify your e-mail address

The first time you sign in to [Merchant Home](https://merchantportal.xplorpay.net/), you must verify your email address.

1. Sign in to Merchant Home.
2. Open the verification e-mail sent to the address associated with your username.
3. Select the verification link in the e-mail, or enter the verification code on the screen.

After you verify your e-mail address, add a phone number. You can use SMS text messages to verify future sign-ins.

### Verify a returning sign-in

Merchant Home uses e-mail verification by default. To use another method, select **Verify with something else** on the verification screen.

### Manage SMS verification

To update your SMS verification settings, select the dropdown under your username in Merchant Home. Then update your security settings.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.xplorpay.com/getting-started/set-up-multifactor-authentication.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
