Qualcomm Snapdragon X may achieve better success if they followed Apple's path (a well rounded dev kit), and makes Linux first class support instead of Windows with the Copilot+ PC which proven is a dumpster fire.
That's not how Passkey, and the underlying WebAuthn works.
(Highly simplifies but still a bit technical) During registration, your key and the service provider website interacts. Your key generated a private key locally that don't get sent out, and it is the password you hold. The service provider instead get a puclic key which can be used to verifiy you hold the private key. When you login in, instead of sending the private key like passwords, the website sent something to your key, which needs to be signed with the private key, and they can verify the signature with the public key.
The CXP allows you export the private key from a keystore to another securely. Service providers (Netflix) can't do anything to stop that as it doesn't hold anything meaningful, let alone a key (what key?), to stop the exchange.
One is a new technical specification called Credential Exchange Protocol (CXP) that will make passkeys portable between digital ecosystems, a feature that users have increasingly demanded.
If malicious apps can make it way to Play Store, this means it is not 100% safe and make it subject to the same security warnings is reasonable, and not give it exceptions and makes it like the only safe option.
Think what happen M$ decided to scrap the new data center, or straight up not buying power from the plant? What if the plant can't make a profit? Who is going to pay when it defaults? What if there's a slip up and end up the next Chernobyl? Of course, it's taxpayer who pay all.
