Android Automotive will let you PIN-lock apps to keep them private from passengers

Google is set to enhance the privacy features of its Android Automotive operating system with the introduction of a native App Lock feature. This new functionality, referred to as sensitive app protection, allows users to secure specific applications behind a unique PIN, distinct from the primary profile lock that governs access to the vehicle’s infotainment system.

Enhancing Privacy in Shared Spaces

In contrast to personal Android devices, vehicles equipped with Android Automotive OS serve as shared environments. While the system does support individual, PIN-protected user profiles to maintain data separation, it has previously lacked a mechanism to lock specific applications. This gap has created a potential privacy concern; for instance, unlocking a profile for a passenger to play music inadvertently grants them access to other sensitive apps. The introduction of the App Lock feature aims to address this issue.

According to recent release notes for Android Automotive’s unbundled apps, the sensitive app protection feature will empower users to lock third-party applications such as Chrome or WhatsApp, ensuring that personal data remains confidential even when the rest of the infotainment system is accessible to others. However, the implementation of this feature will depend on individual automakers, as Google is releasing it as an unbundled app, similar to its standalone dashcam tool.

The underlying service, labeled Sensitive App Lock, will introduce a new entry under Settings > Privacy. The system succinctly describes its purpose: ‘Lock apps to stop other people opening them.’ Users will find a toggle to activate the feature, along with a ‘My Apps’ section that lists currently secured applications. It is important to note that while the feature disables the user interface of locked apps, they may still operate in the background and share data with other applications.

When enabling the App Lock, users will be prompted to create a 4-to-16-digit PIN. In the event of a forgotten PIN, it can be reset by signing into the associated Google Account; however, this process may require the deletion of locked apps or their data to ensure security. Once set up, users can choose which apps to lock, although essential system tools like Assistant, Maps, and Settings will remain accessible.

Interestingly, Google is also developing a native App Lock for Android phones, which is expected to be released as a public API in the upcoming Android 17 update. The key distinction between the two versions lies in their implementation: while the phone version serves as a developer tool, the Android Automotive’s Sensitive App Lock is a fully realized feature ready for deployment by automakers.

As the documentation for this feature has only recently become available, it is unlikely that any automaker has had sufficient time to integrate it into their vehicles. However, for those driving an Android Automotive vehicle, the anticipation of seeing this feature on the dashboard is certainly building.
