Google is introducing a native App Lock feature for its Android Automotive operating system, allowing users to secure specific applications with a unique PIN, separate from the primary profile lock. This feature, called sensitive app protection, addresses privacy concerns in shared vehicle environments by enabling users to lock third-party apps like Chrome or WhatsApp. The App Lock feature will be accessible under Settings > Privacy and requires users to create a 4-to-16-digit PIN. If forgotten, the PIN can be reset by signing into the associated Google Account, potentially requiring the deletion of locked apps or their data. Essential system tools will remain accessible, and the feature's implementation will depend on individual automakers. Google is also developing a similar App Lock for Android phones, set to be released as a public API in the upcoming Android 17 update.
