How to create menu in joomla 3 with "user" item?

Question

Joomla

I'm learning joomla 3 for my graduation project. Got a question. It is necessary to implement a menu, where there are some items for the authorized ones, others for the non-authorized ones, and others for the administration:

In place of the "user" there should be his name, and in the drop-down item the items available for his access level. The standard module does not fit and in general I don’t want to search on the Internet. Is it necessary to implement, due to the fact that you need to get a username, a module, or can you create it in a template?
