Is it mandatory to show user name next to the user icon?
I've come across this simple question while designing an application. The application requires a person to login to the system. When logged in, there will be an icon on the top right of the header which will have a context menu.
Now I've decided it to look in the following way.

Now is it mandatory to show the user name next to the icon? if so, could any one explain me the rational in it.
Thanks
