How to export an HTML in flexdashboard so other people whithout R can visualize it?

I am new to dashboards in R, I used flexdashboard to make one and it gives me the option to export it to HTML but as it is a local document only I can view it. How can I make others who do not have R downloaded to view my dashboard? (And if there is any way to put a password, it would also be very useful) Thank you
