# Require two-factor auth

Two-factor authentication (2FA) adds a second authentication method on top of username and password. This increases account security. n8n supports 2FA using an authenticator app.

## Enable 2FA <a href="#enable-2fa" id="enable-2fa"></a>

You need an authenticator app on your phone.

To enable 2FA in n8n:

1. Go to you **Settings** > **Personal**.
2. Select **Enable 2FA**. n8n opens a modal with a QR code.
3. Scan the QR code in your authenticator app.
4. Enter the code from your app in **Code from authenticator app**.
5. Select **Continue**. n8n displays recovery codes.
6. Save the recovery codes. You need these to regain access to your account if you lose your authenticator.

## Disable 2FA for your instance <a href="#disable-2fa-for-your-instance" id="disable-2fa-for-your-instance"></a>

Self-hosted users can configure their n8n instance to disable 2FA for all users by setting `N8N_MFA_ENABLED` to false. Note that n8n ignores this if existing users have 2FA enabled. Refer to [Configuration methods](/deploy/host-n8n/configure-n8n/basic-configuration.md) for more information on configuring your n8n instance with environment variables.

## 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.n8n.io/administer/manage-users-and-access/verify-user-identity/require-two-factor-auth.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.
