Hello first time umbracian here, making my debut on the forums! ;)

Im building a web shop wherein retailers have the possiblity to edit and update their customers, I've built a standard form where the retailer can change member properties for their customer like name, email, shipping information and so on, but I can't find a way to programmatically change the member's login name.

Im retrieving the member using the MemberService found in Umbraco.Core but can't find no way to get/set the login name.

Code snippet:

        // Update umbraco member
        var member = Services.MemberService.GetByUsername(customer.LoginName);
        member.SetValue("firstName", model.FirstName);
        member.SetValue("lastName", model.LastName);
        member.Email = model.Email;
        // change member login to match member email (email is login name)
        Services.MemberService.Save(member);

I did some searching on the forums before I decided to create this post and most topics were a couple of years of old and didn't provide a solid answer to this question, maybe some of the more seasoned Umbraco devs could help me out?
