# Initial login - protecting your MFA secret key (RUX)

Please note!! - This article is ONLY for customers using Vectra's Respond UX. If you are unsure which UX you are using, please see: [Vectra Analyst User Experiences (Respond vs Quadrant)](/deployment/getting-started/analyst-ux-options-rux-vs-qux.md) for more information .

## Adding MFA with Secret Key Backup

When you first access the Vectra AI Platform, you will be prompted to set up multi-factor authentication on your mobile device. A prompt will appear to scan a QR code that contains a secret key.

Once the QR code is scanned, linked to your authenticator app, and the six-digit code inputted into the Vectra, you will receive a secret key. This secret should be saved to provide a backup for creating a different authenticator app for the user.

To use the Secret Key to register a new authenticator app, manually add the saved secret key when prompted in the app. The opportunity to register by secret key is prompted in the same flow as when a QR code is scanned. Account names are to help track what the key should be associated with.

## 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://docs.vectra.ai/deployment/getting-started/respond-ux-deployment/initial-login-protecting-your-mfa-secret-key-rux.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.
