> “Users no longer need to enroll each device for each service, which has long been the case for FIDO (and for any public key cryptography)," said Andrew Shikiar, FIDO's executive director and chief marketing officer. "By enabling the private key to be securely synced across an OS cloud, the user needs to only enroll once for a service, and then is essentially pre-enrolled for that service on all of their other devices. This brings better usability for the end-user and—very significantly—allows the service provider to start retiring passwords as a means of account recovery and re-enrollment.”

I'm not so sure I like the idea of my private keys being synced to "the cloud". I much prefer my current workflow where my yubikey is the sole owner of my private key. It is unclear to me if I will be able to continue using this method with passkeys.
