I am very new to Auth0, and right now I am maintaining an existing project with auth0 already setup.
Currently, it has an issue as the below reproduce steps:
- User sign up with facebook with email addr: firstname.lastname@example.org
- User sign up with email with the same his email’s from facebook
Our system ends up with 2 separated accounts.
The expected behaviour should be: prompt that there is an existing user, and do you want to join?
I don’t know where the logic exists, could anyone give me some hints? Thanks
