Applies To
- Universal Login
- Sign Up Fields
Solution
Currently, it is not possible to pass a URL parameter similar to or equal to the login_hint to pre-fill custom sign-up fields. The login_hint URL parameter can only be used to pass the identifier of the user to the Universal Login login page. To suggest this functionality in a future release of Auth0, please submit a feature request using the Product Feedback form.
