Android sideloading to include additional steps under Google’s ‘Accountability Layer,’ company confirms

Google has confirmed plans to introduce a new “high-friction” installation flow for sideloaded apps on Android, signaling a change in how users install software outside the Google Play Store. The company says the update is designed to increase user awareness around security risks rather than restrict sideloading altogether.

The confirmation follows recent indications in Google Play system strings that pointed to changes in sideloading behavior. Responding publicly, Google stated that the upcoming flow will add additional steps and warnings when users attempt to install apps from unverified sources. According to the company, the goal is to ensure users clearly understand the potential risks associated with sideloaded applications.

It’s not a sideloading restriction, but an "Accountability Layer." 🛡️ Advanced users will be able to"Install without verifying," but expect a high-friction flow designed to help users understand the risks.

Google describes the new approach as an “accountability layer.” Advanced users will still be able to proceed with sideloaded installations, including an option to install apps without verification. However, choosing that path will involve extra prompts intended to highlight factors such as developer verification status, network requirements, and possible security implications.

Early indications suggest the updated experience aligns with recent changes already appearing in newer versions of Google Play, where warning messages around sideloading have become more prominent while still allowing installations to continue. The revised flow is expected to apply to devices running Android 8.0 and later, where users must already grant individual apps permission to install software from unknown sources.
