Is it possible to automatically create an account for customers when they open an issue with our support team via an email to jira service desk vs, having them have a link sent in the reply email i.e. "view your request in our portal?" Basically I need to know if when a customer sends in a service request via email can they just have a link that logs them in automatically, or do they always have to do the inital sign up with their full name > add their password to view the status etc of their request?
