It's a user, personally, I hate these things. I almost always have my password vault at my fingertips. And I just want to paste my damned password. Instead now I got to flip over to my email app, hope to hell that the email actually arrives in a timely manner, etc. If it was available is an option? Fine. But I've seen people to use these almost exclusively is the login mechanism. Hate it. It's not that it doesn't work, it's just inconvenient for me more often than not.

I hate the actual incarnation of passkeys because they're designed to take control from the user. But I hate this even more, take control and promote the bad practice of clicking weird links from email. When my bank sends me an email I never even use the link to open their homepage, I'll know where to find it. Bypasses phishing attempts from the bad guys as well as the lovely tracking parameters the other bad guys put in there.
