Installing apps from sources outside the official Google Play Store, known as sideloading, was once a straightforward process on Android devices. Users simply had to download an APK file, permit installations from unknown sources, and grant necessary permissions. However, this simplicity is changing as Google tightens its security measures to protect users from potentially harmful software.
Recently, Google launched an early access developer verification program meant for app creators who primarily distribute their apps outside the Play Store. Alongside this, Google has outlined plans to restrict sideloading capabilities to so-called "experienced users" — mainly developers and power users — who are considered more aware of the risks involved in installing unverified applications.
"We are developing a new advanced process that empowers experienced users to knowingly accept the risks associated with installing software that doesn’t go through verification," said Matthew Forsythe, Director of Product Management for Android App Safety.
"This process is carefully designed to prevent users from being coerced or tricked into bypassing important safety checks, especially under pressure from malicious actors."
"It will feature prominent warnings to ensure full awareness of the potential risks, ultimately leaving the decision in the users' hands."
This “advanced flow” for developer verification remains in development, and Google is actively seeking feedback from stakeholders over the coming months. The implementation of this sideloading requirement is scheduled to begin in 2026, initially rolling out in select countries such as Brazil, Singapore, Indonesia, and Thailand, with plans for broader international deployment later in the year.
