Exclusive: Google’s secret ‘Project Toscana’ fixes the Pixel’s biggest face unlock flaw
Source: Android Authority
TL;DR
- Google is developing a new advanced face‑unlock system called Project Toscana for Pixel phones and Chromebooks.
- Toscana is designed to work better in challenging lighting conditions than the current Pixel face‑unlock feature.
- This aligns with earlier reports that Google is working on an IR‑based face unlock for the Pixel 11 series.
Introduction
Since Apple introduced Face ID on the iPhone X in 2017, Android phones have struggled to match its reliability. Recent information suggests that Google may finally close the gap with its own advanced facial‑recognition project.
Project Toscana Overview
According to an anonymous source, Android Authority learned that Google is testing Project Toscana, a facial‑recognition system intended for both Android phones and Chromebooks.
- Testing locations: UX testers in Mountain View, CA.
- Devices used: A Pixel phone with a single hole‑punch camera and two Chromebooks with external cameras (prototype hardware with exposed circuitry).
- Lighting conditions: Tests were conducted under various lighting scenarios, and the system performed as quickly as Apple’s Face ID.

The exact technology behind Project Toscana has not been confirmed, though infrared (IR) is the most likely candidate. It represents a more advanced approach compared to the current Pixel face‑unlock feature, which relies solely on the front‑facing camera.
History of Face Unlock on Pixel Devices
- Pixel 4 series: Used radar sensors and IR cameras for 3D facial recognition. The feature was discontinued after a year.
- Pixel 7 series: Re‑introduced a basic face unlock using the front camera, limited to unlocking the lock screen.
- Pixel 8‑10 series: Added machine‑learning‑enhanced face unlock that supports Google Pay, banking apps, and other secure logins. This works well in well‑lit environments but struggles in low light.
Expected Improvements with Project Toscana
Project Toscana aims to combine the best aspects of previous implementations:
- Accurate recognition in any lighting condition without requiring additional visible hardware beyond a single front‑facing camera.
- Potential for under‑display IR camera (as previously reported for the Pixel 11 series), though the final design may retain a hole‑punch.

Future Timeline
- Pixel 11 launch: The source suggests Project Toscana could ship with the Pixel 11, expected in August 2024.
- Chromebook integration: A release for Chromebooks is less certain; a 2026 timeframe is considered plausible.
Google has not publicly commented on Project Toscana. With Google I/O approaching, the company may showcase the technology during the keynote.
