Thanks @dan.woda for the link.
Unfortunately this document does not refer to the NEW universal login with page templates (Liquid templates) and the management API I was asking for.
I would like to understand how to implement what it is declared supported in the “New Universal Login vs. Classic Universal Login” page I linked above.
Thanks,
Gualtiero
The point in the doc you linked is simply saying you can create your own custom pages (you host) and link to them from the login page by updating the page template.
For example, you can add a link in the footer for your self hosted custom signup or pw reset page. It may also be possible to replace the existing signup or pw reset links with some JS, but we don’t officially support changes within the widget.
