I want to explore possibilities of following use case
Given user is using the same AppleID on all their devices.
1 - User registers on their Macbook Safari Browser.
2 - User opts in for passwordless login and saves passkey on their Macbook.
3 - User goes to same website on the safari browser on their iPhone.
4 - User is logged in passwordless thanks to shared keypass via icloud keychain.
Currently I havent seen an example where this works and user is asked to turn on bluetooth and scan a QR code. Could you let me know if this is possible or if there is an example on production?
