You can try it currently - set an iOS device as a development target in Xcode, go to the iOS developer menu (settings->developer) and turn on the passkey option[0]. Then, on a desktop or laptop with Bluetooth and in a Chromium-based browser, attempt to enroll a security key on a website that supports Webauthn - Chrome will popup the prompt to "add a new Android device", which will then show a QR code that you can scan on your iOS device. It'll prompt you to enroll a security key with the text about "save a passkey for this account in iCloud Keychain"[1]. In reality, all it does is create and sync fresh security key private keys for use across devices, with interoperability over BLE so it's easier to use them even if you don't have an expensive iMac. 0: https://developer.apple.com/documentation/authenticationservices/public-private_key_authentication/supporting_passkeys https://developer.apple.com/documentation/authenticationserv... 1: https://photos.app.goo.gl/5LwhDsXbWg4yb6326 https://photos.app.goo.gl/5LwhDsXbWg4yb6326
