NETGEAR switch integration

I am new to Home Assistant and I want to integrate my NETGEAR switches (GS308T, GS105Ev2). Via web I only can login to these devices with a password. Via the integration it asks me for a user name. The default username (admin) is not accepted.
My question is: Are these NETGEAR switches supported? If they are: how to overcome this problem?

Likely, the user is root

It was worth a try, but that did not work.
