We are migrating from Auth0 to Keycloak. Auth0 has the concept of Connection Type because of which users with the same email address can exist across connection types - Google, LinkedIn, etc.

By default, Keycloak does not allow duplication of email address as per this thread. The email address needs to be unique as it used for login.

When the users have the same email address across different social connector types like Google, LinkedIn, etc., separate users need to be created in Keycloak based on the social connector type which will help migrate users from Auth0 to Keycloak. Is there a way to achieve this in Keycloak?

There is a Keycloak issue here about multiple accounts sharing a same email but I do not understand whether it is relevant to my question.
