Anonymous user access to dashboard

I noticed that on my Piwik dashboard you are not required to login to be able view user activity for my websites.

Is there any way I can set this up to make it require that all users have login prior to viewing analytical data via the dashboard?

Log into your Piwik site with your Superuser credentials.

At the top of the page, to the right of your userid, click on the down arrow, and then within the pop-up menu click on “Settings”.

Within the “Manage” menu, click on “Users”. For the “anonymous” user, for each of the web sites tracked by your Piwik installation, select the “NO ACCESS” option.
