I'm wondering if i get 10 tokens to first time set up qlik sense server, do i "lose" one of the tokens for the super-user access needed to be created during installation? May i only use this access from directly on the server or may i get in from any other computer, too?
Is the super-user access only for QMC or may it be used for normal things like creating apps and visualizations, too?
If you want a user to be able to access the Hub (including create apps / visualizations) then they will need a token. As Martin pointed out above, you do not need to assign a token to the user who installed Qlik Sense Server, though you can allow other users the ability to view the Monitoring Apps stream.
If you do not want to assign a user a token but want them to be able to create apps / visualizations then they can always create apps using Qlik Sense desktop then import them into Server.
