Who can follow my website link to see my FB livestream?

I am responsible for providing our church website users with a way of seeing a FB livestream, which is streamed each week at the same time of day.
The reason for employing the website in this way is that we believe some of our churchgoers have FB phobia and don't usually go near it.
My question is do people have to have a FB account to see a video on the Live tab of our Facebook page, and if the answer is no, are there likely to be any other obstacles to them clicking from our website to see it, such as the device or device OS they are using?
