Problem with configuration page in the gui

Hi! I have installed hass.io from the home page and added myself as user with a username and password. I can open the gui from web browser and had added the MQTT add-on from the shop. Then the installation docs tell me to add a user from the configuration page. But I don’t have this option in my page. Just Person and Zone.

And when I try to logon to the Pi4 server with a monitor and keyboard it won’t accept my username and password. Can anyone put me in the right direction?

Kind regards
Per Arne
