# Create Custom Enrollment Tickets

If you want to customize and manage your users' [Multi-Factor Authentication (MFA)](/docs/secure/multi-factor-authentication) enrollments, you can use Custom Enrollment Tickets. Auth0's Custom Enrollment Tickets generate a single-use link to direct your users to enroll in <Tooltip tip="Multi-factor authentication (MFA): User authentication process that uses a factor in addition to username and password such as a code via SMS." cta="View Glossary" href="/docs/glossary?term=MFA">MFA</Tooltip> with the [factor(s)](/docs/secure/multi-factor-authentication/multi-factor-authentication-factors) you specify.

### Use cases

Use Custom Enrollment Tickets for:

* Onboarding new users
* Configuring user settings
* Specifying factors you want customers to choose during enrollment
* Allowing users to enroll more than one factor

### Configure Custom Enrollment Tickets

Make a post call to <Tooltip tip="Management API: A product to allow customers to perform administrative tasks." cta="View Glossary" href="/docs/glossary?term=Management+API">Management API</Tooltip>'s [`/guardian/post_ticket`](https://auth0.com/docs/api/management/v2#!/Guardian/post_ticket) endpoint.

Management API returns an enrollment ticket containing a `ticket_id` and a `ticket_url`. The `ticket_id` is for internal use. Deliver the `ticket_url` to the user with the `send_email` parameter to kick off the enrollment process. Tickets expire after 5 days and are single-use. A user who receives a ticket will only be able to enroll once.

Sample response:

```json lines
{
  "ticket_id": "gten_8b2f5e90d2c848dc9230d34f",
  "ticket_url": "https://guardianadnrdoifcmtest0.eu.auth0.com/guardian/enroll?ticket=gten_8b2f5e90d2c848dc9230d34f"
}
```

If you enable [Multiple Custom Domains](/docs/customize/custom-domains/multiple-custom-domains), you need to include the `auth0-custom-domain` HTTP header. To learn more, review [Multiple Custom Domains](/docs/customize/custom-domains/multiple-custom-domains#customize-email-handling-using-the-management-api).

### Custom Enrollment Tickets with Classic Login

If you are using the [Classic Login](/docs/authenticate/login/auth0-universal-login/universal-login-vs-classic-login/classic-experience) experience and need to customize how the page looks when the user navigates to the `ticket_url`, you can edit the MFA page.

1. Navigate to [Dashboard > Branding > Universal Login > Advanced options > Multi-factor Authentication.](https://manage.auth0.com/#/mfa_page)
2. If **Customize MFA Page** is not selected, toggle this option on.
3. Update the `ticket` variable.
   Example:

```liquid lines
{% if ticket %}
<h4 class="message">Welcome, {{ userData.email }}, enroll your device below</h4>
{% else %}
<h4 class="message">Welcome back, {{ userData.email }}, authenticate below</h4>
{% endif %}
```
