You cannot share Workspaces to users without accounts (unless you count PDFs).
Adobe takes data security seriously.
That said, for users that have accounts but don't want to always log in, like Executives, you could use the Mobile App Dashboards that will load into the Adobe Analytics apps on their phone (the app is supposed to keep the user authenticated so they shouldn't have to keep logging in).
Also, I know that Adobe has a "live view" dashboard in the works (demo'd during last year's summit) where people without accounts can open a dashboard (the report can be set up with a report PW to ensure that the report is seen only by authorized people). I don't know when that will be released.
Or you can use the Adobe Analytics API to create a website that will make API calls for data (I suggest polling data at a set period and storing in a DB) then creating graphing and data visuals on that website pulling from the DB that is storing the API data. We did something like this to create a "live" dashboard to display on the large screen TVs that were set up in our various offices, it rotated through 5 or 6 different visualizations, all designed for display for TV aspect ratio with no need for anyone to manually do any sections or manipulations.
