Biometric Authentication Testing on Real Android Devices

Overview

Biometric authentication testing verifies that an Android app securely and consistently supports fingerprint and facial recognition based login flows. It ensures proper integration with the Android BiometricPrompt framework and validates real user authentication behavior. Testing on real devices helps teams confirm biometric enrollment handling, success and failure scenarios, fallback to device credentials, and compatibility across Android versions and OEMs. Using the Pcloudy platform, testers can validate biometric prompts, permissions, and app stability under real world conditions, ensuring secure and frictionless authentication for end users.
