## Enable Adaptive MFA Risk Assessment

If you aren't ready to enable Adaptive MFA, but want to start training it to analyze login behavior, you can enable Adaptive MFA Risk Assessment independently.

1. Go to [Dashboard > Security > Multi-factor Auth](https://manage.auth0.com/#/security/mfa).
2. Locate the **Define policies** section.
3. In **MFA Risk Assessors**, select **Enable Adaptive MFA Risk Assessment**.
4. Select **Save**.

## Customize Adaptive MFA

You can customize the behavior of Adaptive MFA to provide the best experience for your users while ensuring security. To learn more, read [Customize Adaptive MFA](/docs/secure/multi-factor-authentication/adaptive-mfa/customize-adaptive-mfa).

<Callout icon="file-lines" color="#0EA5E9" iconType="regular">
  Actions that trigger MFA take precedence over default Adaptive MFA behavior.
</Callout>

## Limitations

Assessment information in tenant logs is only available for interactive flows. Auth0 does not support recording assessment information for <Tooltip tip="Resource Owner: Entity (such as a user or application) capable of granting access to a protected resource." cta="View Glossary" href="/docs/glossary?term=Resource+Owner">Resource Owner</Tooltip> Password Grant (ROPG) flows without adaptive MFA enabled. For more information about authentication flow limitations, read [Adaptive MFA](/docs/secure/multi-factor-authentication/adaptive-mfa).
