Display a home page other than the default

I would like to the Elastic home page to display a particular dashboard on login, rather than the default home page. How do I accomplish that? At the bottom of the default home page there is a link, "Display a different page on login." I assume that is where I begin. But, it's not very intuitive. Thank you.

I figured it out. However, the dashboard comes up with the ability for anyone to edit it. Is there a way to make it Read-Only? Thanks.
