Best Practice for Customizing Universal Login/SignUp

Hi-

There seem to be a few different ways (currently) to customize the Universal Login/Signup process.

  1. Editing Partials/Themes/Prompts/Templates through the Management API
    Allows you to overwrite these different elements of the login screens/pages.

  2. Using ACUL SDK
    Gives full control over process.

  3. Using Forms
    Kind of a WYSIWG/ControlFlow GUI

4)Using Actions with redirects
Where you redirect user to page hosted elsewhere (to fill out additional data, eg), then return them to the Auth0 flow

5)AuthJS SDK for full embedded solution in SPA apps

Can someone confirm if I’m summarizing this correctly?

Can anyone speak generally about the use cases that are appropriate for each solution?

Do these solutions have a hierarchy of difficulty?

In particular, can someone recommend the right solution for my use case:
–Using a Custom DB I need to add a few text fields to the signup prompt and allow users to select their employer from a preset list of companies (ajax-driven). These values need to be save to the Auth0 user profile and our custom db connection.

Thanks

Hi @jdrew1,

Here’s a general overview of appropriate use cases for each:

  1. Editing Partials/Themes/Prompts/Templates:
  • When you must align the Universal Login page’s appearance with your brand guidelines or make simple text changes.
  1. ACUL SDK:
  • When you need to modify the behavior or add dynamic elements to the Universal Login page, but still want to leverage Auth0’s hosted solution.
  1. Forms (New Universal Login Builder):
  • When you have straightforward data collection needs during signup and prefer a visual, low-code approach. This is often the first place to look for custom fields unless your requirements are complex.
  1. Actions with Redirects:
  • When you must break out of the standard Auth0 flow to perform an external process and then return. This is ideal for adding robust, application-specific steps.
  1. AuthJS SDK for complete embedded solution:
  • When you require ultimate control over the front-end login/signup experience and are willing to invest in building and maintaining that part of your application.

The difficulty hierarchy generally stands as follows, though it can vary:

  1. Forms
  2. Editing Partials
  3. ACUL SDK
  4. Actions with Redirects
  5. AuthJS SDK

Given the requirements of your request, here’s my recommendation:

  1. ACUL SDK on the signup page for the client-side interaction.
  2. A Post User Registration Action to save data to the Auth0 user profile and your custom DB.
  3. A Custom Database Connection script to handle the actual saving to your database.

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

Have a good one,
