Feature: Allow login_hint parameter to work with flexible identifiers on a database connection.
Description: If a user has entered an email address it has a distinct value vs a phone number. The login_hint field would contain an @ symbol if it’s an email address and that could be keyed on to help fill the value via login_hint. On a login page it will take the login_hint as the form uses a phone or email box while the sign-up page is separate.
Use-case: Building a project where we can collect different information in modals on our website and then pass the necessary information to the respective backend services for processing/storage while using Auth0 Universal Login for the sign-up/login flow.
