iphone faceid - There are no matching passkeys saved in your icloud keychain for localhost

[bugthug404]

HI community,

I've implemented webauthn on my localhost according to the example on this repo. it is working fine with macbook touchid & windows hello but not working with iphone faceid showing "there are no matching passkeys saved in your icloud keychain for localhost"

is there anything i am not aware of or any special requirement for iphone faceid?

server response for authentication-option

Hello @bugthug404, those options look fine to me. Are you sure you're using the same iCloud account on both your MacBook and your iPhone? And is Settings > iCloud (the top option that says your name) > iCloud > Passwords and Keychain > Sync this Mac/iPhone turned on on both devices? Those are common reasons why passkeys don't get synced between devices.

Let me know what you find out and we can continue from there.
