Work IT is different from services being offered to the public, though.

The difference is the security requirements. Services that are fine today with you using just a username+password won't care at all if you use a passkey that is considered unsafe.

Yes they will, because of risk aversion and cargo culting. They won't actually audit a passkey provider or have well-defined security criteria, but they will just require what everyone else requires.

Hmm... why don't they already implement their own authenticator apps, if it's just risk aversion and cargo culting? Again it's totally possible and it already exists.

I currently, exclusively use my Yubikeys as passkeys, and it works everywhere where passkeys are available. So I don't personally see a problem.

What I see is that people complain because of some kind of disagreement that happened between some people on the Internet about the passkey implementation in KeepassXC. And nothing about that materialised.
