As someone who works with people too stupid to log in to github without having to reset their password every time and having to take a full hour to figure out how to use their recovery method, that’s going to be a pain in the butt. I can foresee lots of "hey, quick question"s if they really do phase out simpler login methods. It’s good to have options for sure, but the standard login method should stay imo
What do you mean exactly by “not web first?” I use it, and aside from not being able to detect the browser tab name without using the extension, I don’t really see anything that would be missing
