Just sounded cooler , and I was on the team that worked on Passkeys at Microsoft, so I wanted to poke them a bit (in a friendly way).

To me, “hijacking” a passkey sounds like credential disclosure, which is quite worrying for a core team member to talk about. I know what you mean, but it’s probably the wrong term to be using if we want to emphasize that passkeys cannot be stolen.

I completely agree, I spent half the post confused about what exploits they were taking advantage of, and why I _shouldn't_ use passkeys.

+1. I bet it's because of this confusing verbiage, the AI also got the gist of the article wrong, and lead me to believe that this article shows "post-hoc exploit" , when in fact there's no mention of the word 'exploit' in the article. See the screenshot linked below [1].

On a tangent, in the process I learnt that Firefox (at least on desktop) now has an "AI preview" feature where if you long-press on a URL, it brings up the pop-up. The first time, it notifies that the "AI" processing is local-only to preserve privacy.
