The Biometric App Lock Xposed Module is a system-level security modification designed for clean AOSP and Pixel ROMs. It intercepts application launches directly at the Android framework level to enforce native, per-app biometric authentication without relying on heavy third-party software.

I’ve been using this on my daily driver to secure my banking and gallery apps, and it feels completely native to the OS. Because it hooks right into the framework, you don’t get that annoying delay or screen flash that standard app lockers suffer from, completely locking out unauthorized access even from the recents menu.

• Native AOSP security is finally added to clean Pixel ROMs, bringing reliable per-app biometric locks without the bloat.
• Intercepts app launches deeply at the system framework level before the target activity can even be created.
• Absolute recents protection stops anyone from bypassing the security screen by tapping an active app from the multitasking menu.
• Instant lock application means your newly selected apps are secured immediately without needing a full system reboot.
• Requires Android 11+ alongside a modern root manager with full libxposed API support to function properly.

My Verdict

If you run a clean Pixel or AOSP ROM and hate relying on clunky third-party security apps, this module is an absolute must-have. It patches a massive missing feature by bringing unbreakable app locking directly into the core Android framework.
