For an epic good time in seeing how usability and security can both combine to make a living computer hell on earth for end users, go read up on the Microsoft Windows 10 "windows hello" PIN stuff. Especially things like trying to just not have a pin at all, but hitting the brick wall of the remove button being greyed out. The "solutions" include all sorts of horrible brain surgery on the permissions of hidden system folders and/or actual windows registry editing. Just, hilarious. It is almost as if microsoft has not been making operating systems or user interfaces for multiple decades now. Well, of course, this is microsoft (hey, i worked there, i can complain) so yeah they don't actually ever learn or improve. (If you want more evidence of how they shovel things out the door that are suboptimal, you should have had the pleasure of trying to use the pc xbox app.)
