The process of disabling Face ID differs from the five presses of the power button required on older iPhones. The computational power necessary for that process is supplied by the new A11 Bionic CPU and the data is crunched and stored in the redesigned Secure Enclave. Instead, Face ID works on-device only to recognize users. That data was collected worldwide from subjects who consented to having their faces scanned.įederighi explained that Apple retains a copy of the depth map data from those scans but does not collect user data to further train its model. “That wasn’t just something you could go pull of the internet.” Both for testing and validation for great recognition rates,” says Federighi.

“Phil mentioned that we’d gathered a billion images and that we’d done data gathering around the globe to make sure that we had broad geographic and ethnic data sets. Federighi went into depth on how Apple trained Face ID and how it works in practice.

In a telephone interview with Matthew Panzarino of TechCrunch, Apple’s Senior Vice President of Software Engineering, Craig Federighi, answered many of the questions that have arisen about Face ID since the September 12th keynote event. Unless you specifically want to receive 2FA codes from Twitter via SMS, you should consider switching to a dedicated authentication app: these codes work independently from carriers and location, and they can be generated offline.

Here, I tapped the QR button, scanned the QR code Twitter was displaying on my iPad with the iPhone’s camera, and that was it. I then selected to use another app to generate my codes and opened 1Password on my iPhone, where I hit Edit on my Twitter login item and scrolled to the OTP section. Switching from text messages to 1Password (which I use for one-time codes) was easy: in Twitter for iPad, I went to Settings ⇾ Account ⇾ Security, and enabled the ‘Security app’ toggle. This is great news as Twitter was the last service with 2FA that only supported sending codes via SMS.

The company has updated their support document with instructions on how to set it up here. Įarlier today Twitter announced that you’ll now be able to use a third-party app (such as Google Authenticator, Authy, or 1Password) for two-factor authentication instead of SMS.

You’ll now be able to use a third party app for two-factor authentication instead of SMS text messages. We’re rolling out an update to login verification. We continue to develop and test further mitigations within the operating system for the Spectre techniques, and will release them in upcoming updates of iOS, macOS, tvOS, and watchOS. It’s also worth noting that this is probably not the last we’ll hear about Meltdown and Spectre. The gravity of the exploits, which affect virtually all computing platforms, cannot be understated, but it’s reassuring that the initial mitigations released and those coming in the days ahead should have little or no impact on performance. Our current testing indicates that the upcoming Safari mitigations will have no measurable impact on the Speedometer and ARES-6 tests and an impact of less than 2.5% on the JetStream benchmark. Apple is working to address the problem with an update to Safari that will be released in the coming days. Our testing with public benchmarks has shown that the changes in the December 2017 updates resulted in no measurable reduction in the performance of macOS and iOS as measured by the GeekBench 4 benchmark, or in common Web browsing benchmarks such as Speedometer, JetStream, and ARES-6.Īpple’s support document also reveals that Spectre can be exploited in web browsers, including Safari, using JavaScript. If there’s any good news to be found in the widespread concern caused by these exploits it’s that Apple says the recently-released mitigations have no measurable impact on performance: The support article published by Apple provides a high-level explanation of how each exploit works. Development of mitigations for both exploits is ongoing and new defenses will be released to each Apple OS as they become available. Mitigations to defend against Meltdown have already been shipped by Apple in iOS 11.2, macOS 10.13.2, and tvOS 11.2.

Although there are no known exploits of the vulnerabilities, Apple advises that users proceed with caution and download apps from trusted sources only. In a support article, Apple has acknowledged that the recently-disclosed Meltdown and Spectre exploits, which affect virtually every CPU in computers, mobile devices, and other platforms, also impact every Mac and iOS device.
