Must be in the docs somewhere, but I can 't find it.  The installation section gets me to the login screen and leaves me there: "the GUI is available by using the http protocol on port 80 of the Manager server."  Also find nothing in the user accounts and authentication sections.  I searched this site for relevant words too.

What is the root/super account username/password after installing?

(Apologies in advance if it's it's right in front of me).
