Apple’s first foldable iPhone, the iPhone Duo, is described as lacking Face ID and instead relying on Touch ID for authentication. According to reports, Touch ID is used to unlock the device both when it is open and when it is closed, addressing the challenge of fitting a facial biometric system for multiple foldable viewing angles and positions.
AppleInsider and MacRumors both say Touch ID is integrated into the iPhone Duo’s side button. AppleInsider adds that some users who prefer Face ID can use Apple Watch to authenticate automatically. MacRumors similarly notes an option for Apple Watch owners to unlock the iPhone Duo without pressing the button.
Both outlets also reference pre-orders and availability timing, with MacRumors citing a pre-order start at 5:00 a.m. Pacific Time on October 16 and availability beginning October 23. Overall, the coverage focuses on how Apple adapts iPhone authentication choices to the constraints of a foldable form factor, and how Apple Watch can supplement Touch ID for certain users.
