# 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.
