Work update: Since last month, I’m the manager of WebKit Security & Privacy at Apple. Huge responsibility in this day and age, but it's the kind of challenge I like. Here’s a thread about this Silicon Valley team and jobs you can apply to today!

[Jiewen Tan @alanwaketan]

@SilentImp I don’t work for Apple anymore. Feel free to reach out to @webkit.

[Jiewen Tan @alanwaketan]

@pvachonnyc @webkit @jonathandavis Can you please report the bug to https://t.co/7G50Ua9RFm? I’m no longer working at WebKit, but someone from there should be able to investigate further. Appreciate your findings!

[Jiewen Tan @alanwaketan]

@acpsm2 No, it’s not possible.

[Jiewen Tan @alanwaketan]

Over the past few months, I have received a lot of questions regarding to this new technology. I hope this article has addressed them well!

[WebKit @webkit]

Meet Face ID and Touch ID for the web to learn how to adopt these technologies with detailed examples, guidance on managing different browser UI, propagating user gestures to WebAuthn calls, and working with Apple Anonymous Attestation. https://t.co/avAF4u3L7w

[Jiewen Tan @alanwaketan]

@acpsm2 The LocalAuthentication.Framework does provide this facility. However, the WebAuthn API doesn’t define such function at the time this post is published. You can double check the current spec and latest update from WebKit.

Private Click Measurement updates: Click fraud prevention with blinded signatures and attribution reports sent to advertisers/merchants too: https://t.co/8ghYRvruDf

[Jiewen Tan @alanwaketan]

@_sid_gupta @IAmKale It’s supposed to work in M1 Macs. Can you file a bug on https://t.co/7G50Ua9RFm and cc me?

[Jiewen Tan @alanwaketan]

@IAmKale An interesting bug!

[John Wilander 🇺🇦 @johnwilander]

Exciting news! Today's iOS/iPadOS betas have Private Click Measurement (PCM) enabled and it works for both web-to-web and app-to-web. PCM is a new, privacy-preserving way to measure click-through ad campaigns that navigate the user to a website. https://t.co/su3uikurag

[Jiewen Tan @alanwaketan]

@FlxMgdnz @herrjemand We fixed that on STP but it’s not available on iOS yet.

[Jiewen Tan @alanwaketan]

@FlantasticDan Yes, the simulator can’t simulate those hardware accesses.

[Jiewen Tan @alanwaketan]

@_initi @webkit @jonathandavis @rmondello Thanks for your suggestions. Those are really good input!

[Jiewen Tan @alanwaketan]

@StevenBriscoe You could search for WebAuthn sample code, and should be able to find some.

[Jiewen Tan @alanwaketan]

@FlantasticDan Unfortunately, it’s not available in the simulator.

[Jiewen Tan @alanwaketan]

@dannycabrera @webkit @jonathandavis The blog post should have great info for you.

[Jiewen Tan @alanwaketan]

@dannycabrera @webkit @jonathandavis Have you checked error from the web inspector?

[Jiewen Tan @alanwaketan]

@dannycabrera @webkit @jonathandavis What OS version is this?

[Jiewen Tan @alanwaketan]

@dividuum It’s not classified as website data, and therefore it won’t work. Then maybe you should file a radar and prove it’s not working for you.

[Jiewen Tan @alanwaketan]

@dividuum Works for me.
