In the 2000s (before 2010) Facebook would allow you to get a direct URL to one's own Facebook album that could be emailed and shared with non-Facebook users. People have asked this question before like in this question in 2010.
It is now 2019, and those old answers no longer work. Does Facebook still allow that or any other way to share your albums with non facebook people? I want to share my photo album with some of my contacts on WhatsApp and Instagram.
