The big news in the proposal is that it will be possible to use the same passkeys even if you change the platform or service, something that will make it much easier for users than it is now.
Login credentials will be transmitted using Credential Exchange Protocol (CXP) and Credential Exchange Format (CXF), which means, among other things, that they are always encrypted.
Considering that companies like 1Password, Apple, Bitwarden, Dashlane, Enpass, Google, Microsoft, NordPass, Okta, Samsung, and SK Telecom are members of the Fido Alliance, we can probably expect that there is a good chance that this proposal will become a reality in the near future.
