What’s the Optic ID feature on Apple’s Vision Pro headset? How does it work?
Learn about the Optic ID feature in visionOS, including how it securely unlocks Apple’s Vision Pro mixed-reality headset and authenticates purchases.
Apple’s visionOS platform offers a secure authentication feature similar to Face ID, dubbed Optic ID. By taking advantage of the uniqueness of each person’s iris, Optic ID unlocks the Vision Pro headset as soon the user wears it on their head.
Your optical fingerprint is encrypted and securely stored in the Secure Enclave cryptographic coprocessor to protect your privacy. It’s never shared with apps or uploaded anywhere. Here’s how Optic ID works and the technology behind it.
What is Optic ID? How does it work?
Optic ID was unveiled during the Vision Pro and visionOS segments of the WWDC 2023 keynote. Optic ID is a secure biometric system for authenticating Apple headset users. Like Face ID and Touch ID, it’s an interplay of hardware and software.
A series of LEDs arranged into a ring pattern shoot invisible infrared light onto each eye. The inside-pointing cameras take a series of images of the iris under various exposures. The images are fed to the dedicated Neural Engine coprocessor running a machine learning algorithm that compares this data to the enrolled Optic ID data.
If there’s a match, the headset unlocks automatically.
What can you use Optic ID for?
Optic ID protects the same private information on your Vision Pro headset as Face ID and Touch ID do on your iPhone and iPad.
You can use Optic ID in visionOS to:
- Unlock your Vision Pro headset
- Authorize purchases on the App Store
- Authorize Apple Pay purchases
- AutoFill saved passwords on websites and apps
The same system that powers Optic ID also makes precise eye tracking possible.
Optic ID: Security and privacy
Optic ID relies on the uniqueness of your iris. It doesn’t suffer from Face ID’s evil twin problem because even identical twins have unique irises. In that regard, Optic ID is more secure for authorizing Apple Pay transactions than Face ID.
Privacy and security are guaranteed because your iris data is encrypted and stored securely by the Secure Enclave cryptographic coprocessor. This walls off Optic ID data from the rest of the system, making it inaccessible to apps. In fact, only the Secure Enclave can access your Optic ID data.
Moreover, your enrolled Optic ID profile is never uploaded to Apple’s servers, nor is it shared with other companies or third=party apps and websites.
What you’re looking at stays private
According to Apple, what you’re looking at stays private so Apple because visionOS isolates this data in a separate background process.
This is by design so no one, including Apple and third-party apps and websites, can use Optic ID data to guess what you might be thinking about. Only the final selection is revealed to the system when you tap your fingers.
Apple says that data from the Vision Pro’s onboard cameras and sensors is processed at the system level—the headset isn’t beaming everything you see to the cloud.
Also, apps are prohibited from accessing the sensors and cameras directly. “Individual apps do not need to see your surroundings to enable spatial experiences,” reads Apple’s Vision Pro page.
