Yes I think you are right, but this is the correct way I followed in my latest bitnami vm. In my first one I used portal.azure.com as you see in the screenshot.. So I don't have any SSH/FTP access ...
and when I try to connect to the vm by ssh firstname.lastname@example.org it doesn't work

Best and thanks!
