Hi @mc3,
Welcome to the Auth0 Community!
Yes, this is possible by calling the /authorize
endpoint with the screen_hint=signup
query parameter.
It would look something like the following:
https://{yourDomain}/authorize?
response_type=code&
client_id={yourClientId}&
redirect_uri={https://yourApp/callback}&
scope={scope}&
state={state}&
screen_hint=signup
Please note that this will only work with the New Universal Login and will not work with the Classic Universal Login experience.
See this doc to learn more.
Please let me know if you have any questions.
Thanks,
Rueben
