I think they are being pushed because cool technology on paper. Whenever I read an article about them, I can't help but think about the human factors. How are passkeys created, often by a password or email. okay... that looks a lot like a password. Oh you lost the passkey, here lets send you one again. It stinks of a second factor without a first. Sure, the passkey itself is hard to compromise, but how about its creation. If your email is compromised I see no difference from passwords or passkeys.
