How to handle iOS 18 password app autosuggestion to use passkey

[sinchang]

My app uses the @simplewebauthn/browser package with Conditional UI. On iOS 18, password managers auto-suggest passkeys, triggering the passkey prompt. However, we don't receive a callback after the user completes Face ID.

the behavior like in below video

Hello @sinchang, you're saying the call to startAuthentication({ ..., useBrowserAutofill: true }) isn't ever resolving after successfully using conditional UI? In what iOS browser are you experiencing this in? iOS Safari?

Can you provide some code and reproduction steps please? This is very strange.
