> passkeys lubricate the path towards an ever-increasing login-based society where it becomes much easier to track and monitor your online behaviour This trend is already in motion thanks to the deprecation of 3rd party cookies and Apple's restriction of device identifiers, etc, on iOS. For most advertisers these days, the only way to run retargeting campaigns or measure conversions is with 1st party data. That means people are no longer relying on cookies at all for much of their conversion tracking. Instead, email addresses are used. This is (I think) an unintended side effect of stripping away cookies. At least with cookies, you could delete them locally. But now so much tracking is done with first party data, cookies are playing much less of a role. And of course there's not an easy "delete all first party data" button in your browser because the data is (obviously) held outside the browser.
