Customize Universal Login template on non-custom domain

I want to customize the Universal Login page template by adding some custom URL in the URL form for the users (like additional sign-up form link and T&C). I found out the guide:
auth0[dot]com/docs/customize/login-pages/universal-login/customize-templates

But it mentions:

To use customized page templates, you must configure a Custom Domain for your tenant. Further, you can only update Universal Login page templates with the Management API.

That’s a bad news for me as the business I work with doesn’t want to use a custom domain. Is there any way to customize the Universal Login on Auth0’s domain or I need to switch to Classic Login and build template there?

Hi @konradalfaro,

Welcome to the Auth0 Community!

Unfortunately, you will need to set up a custom domain to customize the Universal Login Prompts. You must use the Classic Login Experience to add the prompts you desire.

If you have any other questions, feel free to reach out.

Have a good one,
Vlad
