A person could use different e-mails to create multiple user accounts. This is especially bad if there is something like a free trial period or similar. Therefore, I want to request if auth0 can help to detect if a person creates multiple user accounts and inform the application owner.
E.g. detecting if someone logs in with different e-mails for the same application from the same IP address.
E.g. if different e-mails have the same password hash.
