# Add Bot Detection to Passwordless Flows

If you use <Tooltip tip="Passwordless: Form of authentication that does not rely on a password as the first factor." cta="View Glossary" href="/docs/glossary?term=passwordless">passwordless</Tooltip> login and signup flows, you can enable <Tooltip tip="Passwordless: Form of authentication that does not rely on a password as the first factor." cta="View Glossary" href="/docs/glossary?term=Bot+Detection">Bot Detection</Tooltip> to render a CAPTCHA step in scenarios when a request is determined to be high-risk by Auth0.

<Warning>
  If you are using the [Lock SDK](/docs/libraries/lock) with the Classic Login experience, you must update to version 11.35.0 or higher to use Bot Detection for passwordless flows.

  If you are using the [Auth0.js SDK](/docs/libraries/auth0js), you must update to version 9.20.0 or higher to use Bot Detection for passwordless flows.
</Warning>

## Configure Bot Detection for passwordless flows

You can use the <Tooltip tip="Auth0 Dashboard: Auth0's main product to configure your services." cta="View Glossary" href="/docs/glossary?term=Auth0+Dashboard">Auth0 Dashboard</Tooltip> to configure the behavior of the CAPTCHA feature.

1. In the [Auth0 Dashboard](https://manage.auth0.com/dashboard), go to [Security > Attack Protection > Bot Detection](https://manage.auth0.com/dashboard/#/security/attack-protection/bot-detection).
2. Locate the **Response** section.
3. For the **Enforce CAPTCHA for passwordless flows** setting, select when to require CAPTCHA:

   * **Never**: Users are not required to complete a CAPTCHA to log in.
   * **When Risky**: Users are required to complete a CAPTCHA if the login is high risk.
   * **Always**: Users are always required to complete a CAPTCHA to log in.
