Detecting Platform used to generate/store the passkey (iCloud, Google Key, Windows Hello)

[ChxGuillaume]

Hi everyone,

I gave a look at the documentation and different posts on GitHub and couldn't find any information regarding the possibility to detect which "platform" was used to generate the passkey.

I saw the fmt "AttestationFormat" option but after testing it most of the time returns me "none" or "package" only 😢

I know there is the "credentialDeviceType" that allows you to know if it is saved on a keychain or not (iCloud / Google) but still isn't descriptive enough.

Any idea if that is possible using SimpleWebAuthn's library?

Hey @ChxGuillaume I'm at Identiverse this week so I'll be a bit slow to respond. I definitely have thoughts about this, though, so I'll follow up as soon as I can ✌️
