We are woring on a migration project for a portfolio management company that has custom signup process (similar to ID proofing). App first collects the user details and unit holder number to validate against a registry system before letting user create an account.
We would like to move this signup process to Auth0 for a better attack protection by building a similar signup form that can validate the collected details against an API. Upon successful validation navigate the user to set a username and password, verify mobile and email attributes.
After thorougly going through the documentation we understood that Auht0 can’t render Forms for pre-user-registration trigger. The approach we are thinking is,
- Customize the signup form by inserting custom fields
- Create an action to call downstream API
What we really don’t want herte is collecting the username/email address attributes in the same form until the backend validation is successful. Also we are currently doing a lazy migration which requires dedup checks against another backend API.
Any advise on how these type of usecases can be handled with Auth0?
