Multiple device support for passkey.

I am integrating passkeys in my application. I want to integrate multiple device support using passkey, but I am not able to find any resource how can I handle multiple devices using WebAuthn protocol.

Passkeys are always backed up and synced among your Apple devices. There's special you need to do on top of standard WebAuthn. You can check out the Meet passkeys WWDC session for more details.
