Face2FA is a PHP face authentication solution packaged in a single PHP file. It is designed for quick integration into existing PHP applications without requiring external dependencies.

The system combines PHP, JavaScript, and CSS in one file and automatically handles directories, storage, and sessions during setup. Its interface includes responsive authentication modals with camera guidance.

Face2FA includes security features such as CSRF protection, rate limiting, and secure session management. Face data is designed to remain on the user's device with local processing, providing a privacy-focused authentication approach.

The default storage uses JSON files and can be extended to MySQL or other database systems. Integration is designed to be simple, with the core implementation requiring a single PHP include.
