Embedding reports publicly and privately.

Hi tjowen ,

For your first question, you can refer to the link: https://docs.microsoft.com/en-us/power-bi/service-publish-to-web#limitations .When you use Publish to web, anyone on the Internet can view your published report or visual. This requires no authentication and includes viewing detail level data your reports aggregate. 

For your second question, in the Power BI service, you can share embedded reports with users requiring access. If you're using an Office 365 Group, you can list the user as an app workspace member. For more information, see how to manage your app workspace in Power BI and Office 365.

Best Regards,

Amy
