Hi @phodye,
Welcome to the Auth0 Community!
Yes! You could call the Authentication API’s Get user info endpoint using the access token generated from the user’s initial login to populate the fields in your form.
Alternatively, you could call the Management API’s Get a user endpoint or the Search users by email endpoint to get the user’s information. However, this will require you to know the user’s user_id or email.
Please let me know if you have any questions.
Thanks,
Rueben
