Apple's Optic ID will let you log in to the Vision Pro headset with your eyes

Apple's Vision Pro headset will introduce a new approach to security in the company's products: your eyes. The mixed reality device will use a previously rumored Optic ID system that studies your irises through invisible LED light exposures, and compares it against your enrolled eye data to sign you in. You can use it as a password replacement and to make purchases in the App Store or using Apple Pay.
