Google is introducing new requirements for sideloaded apps on Android, which will start rolling out in October 2025 and become mandatory in September 2026. This move is seen as a limitation on the openness of the Android ecosystem, as it will require developers to verify their identity using government-issued documents or contact information. The change aims to improve security, but some argue it may stifle innovation and hurt independent developers. The new rules will not remove sideloading entirely, but will create friction for users who install apps outside of the Play Store.
