Feature Request: Implement Face Lock

Overview

Introduce a face lock authentication feature in UBlock to enhance security for users. This feature should allow users to set up face recognition as a method to unlock access within UBlock, providing a biometric alternative to password or PIN-based authentication.

Requirements

• Integrate a facial recognition library compatible with supported devices/platforms.
• Provide a setup process for users to enroll their face securely.
• Ensure enrolled facial data is stored securely and never leaves the device.
• Provide clear UI/UX for enabling, disabling, and troubleshooting face lock.
• Fall back to existing authentication methods if face lock fails or is unavailable.
• Document privacy considerations, especially regarding storage and handling of biometric data.

Acceptance Criteria

• Face lock setup, enrollment, and authentication flows are implemented and working.
• Security and privacy requirements are met and documented.
• Feature is tested for usability and edge cases on all supported platforms.

Additional Notes

• Follow best practices for biometric data privacy
• Adhere to platform-specific guidelines for facial recognition APIs (e.g., Android Face API, iOS Face ID)
