I'm the author of the guide (and did this recent update to it), so feel free to ask me any questions you might have. Comments or corrections also welcome.
This renders really weird on FF on windows. Lots of long images. (Yes, some people still use FF and Windows.)<p>Liked the references section, and appreciated some of the finder details (the origin check, for example).
What do you think about MFA, password-less SMS or email based login. It seems there are a lot of varying opions on the topic.<p>This could be an additional topic to add to your guide.
Thanks.
