Android Sideloading Made Harder: Google Introduces 24-Hour Wait Period

Google has introduced a new verification process for Android apps, requiring a deliberate 24-hour wait period for users attempting to sideload software from unverified developers. This move is part of Google's effort to bind app creators to real-world identities, making it harder for malicious actors to distribute malware.

The new 'advanced flow' verification process acts as a bridge ahead of Google's broader enforcement of mandatory developer identity checks on certified Android devices. To sideload apps from unverified developers, users must complete a multistep sequence that includes accessing Developer Options, confirming their screen lock, and reviewing anti-coercion warnings.

The setup is a one-time configuration across a user's ecosystem, with a 10-minute grace period if it is accidentally disabled. Enforcement formally begins on September 30, 2026, across Brazil, Indonesia, Singapore, and Thailand, before being rolled out globally in 2027.
