> I'm sure it's of use to many people but it's been no end of pain for me and it has really signaled to me what it's like to grow into an old man unable to use computers when I was once a young man who would find this easy.

My only "good" solution for passkey UX is to make sure all my devices are Apple. Apple's password/keychain integrates reasonably well enough with Chrome, I can share passkeys with my cofounder easily in shared folder (he is also all-in on Apple ecosystem) and I can share passkeys with my work computer (different AppleID) for low-stakes things like news websites or Amazon.com (I work in IT security for the org, so I know exactly how much I can trust my employer)

I do also use Linux and Windows personally, and the passkey story is much worse there, particularly for Linux which doesn't seem to play well with my Yubikeys. Luckily, a lot of websites seem to have a "Scan this QR code with your iPhone" feature to complete the passkey authentication.
