Looks like a huge amount of security vendors are working to have a secure and open standard for passkey portability between platforms.
It is always good to see major collaboration in the security space like this considering the harsh opinions that users of some of these vendors have toward many of the others. I just wish apps and sites would stop making me login with username and password if passkeys are meant to replace that lol.
Seems like people in the comments are misunderstaning the announcement entirely. This protocol is about import and export from password managers and not about having them synced between devices. It would prevent a lock in effect. This is a great development!
