Hi @kwst,
Welcome to the Auth0 Community!
I understand that you would like to have the signup option on the New Universal Login Page.
First, the New Universal Login Page has a signup option by default on the UI. Have you gotten a chance to try it?
Alternatively, you can pass the screen_hint=signup
query parameter in your /authorize
request to show the signup page. For example:
https://YOUR_DOMAIN/authorize?
response_type=code&
client_id=YOUR_CLIENT_ID&
redirect_uri=https://YOUR_APP/callback&
scope=SCOPE&
audience=API_AUDIENCE&
state=STATE&
screen_hint=signup
After doing so, your users can signup on to your application.
Lastly, you may find the New Universal Login Experience - SignUp doc useful.
Please let me know if you have any questions.
Thank you.
