I don’t understand this point at all. I think the author has himself confused with the average consumer. For the first time in a decade or so you can buy a PHYSICAL key and use it to sign into websites. I can explain this to any grandma out there. Likewise, I’m an Apple user. Once you’re in Apple universe passkeys are extremely easy. Tap your thumb on the scanner, done.
Now we can put on the tinfoil hat and say how this fosters vendor lock in yadda yadda but the last thing I would say is that it has terrible user ergonomics. LOL
