Google is enhancing its Android Automotive platform with a feature called Sensitive App Protection, which allows drivers to secure individual applications with a PIN lock. This feature ensures that sensitive information remains confidential in shared vehicle environments by enabling drivers to restrict access to specific apps while allowing passengers to manage entertainment options. Users can set a unique 4- to 16-digit code for app locks, and recovery is possible via a linked Google Account, although it may involve deleting the locked apps or their data. Most apps from the Play Store can be locked, except for certain system apps like Assistant, Maps, and Settings, which remain accessible. The feature is being rolled out as an unbundled system app, meaning automakers must choose to integrate it, and it will be available through over-the-air updates for vehicles equipped with Google services from various manufacturers. Automakers are expected to restrict PIN entry while the vehicle is in motion for safety reasons.
