Asked for Username and Password when creating dashboard

I am able to login and create a dashboard by creating an ssh tunnel and accessing the web interface at The user I login with has full admin rights. However when I try to create a dashboard I am asked for a username and password as seen in the image below.

Why can’t I login using the user I am logged in with? Can I disable logins when created dashboards for the current user? Should I just enable anonymous logins?
