  > So if I initially create an account from my MacBook and the passkey gets listed as “MacBook”, I then go to log in from my iPhone and it still uses the “MacBook” passkey because of iCloud sync. But this is confusing because I cannot have an iPhone key.

Now try using a Windows or Linux computer...

This is why I strongly prefer to not use OSX passkeys. How the fuck am I supposed to login on my nix machines if you only allow me to enroll one passkey?!

Which Linux? And are you saying Windows an Linux options are better or worse?

I more mean being someone that works in multiple ecosystems.

But FWIW, I have the least friction with Linux. But that's more that Windows and Apple have their walled gardens and that's where the friction comes from, though in different ways.
