Can you really not understand that the github web site still uses passwords? And that these users you describe still need to know and use their github password in order to use github? So all the issues you describe with passwords still exist under github’s current security model. You’re getting that I’m saying that, right? I have more to say but I wanna pause for a second to focus on that point. If github really had replaced passwords with some other approach, or added a layer to their password security (e.g. enforced semi-2FA like Google does) I’d have a whole different take on it.

And, please don’t say things like “much of the confusion.” It’s condescending and wrong to imply that the only possible reason we could be disagreeing is that I’m confused.
