Overview
flutter_2fa is a Flutter package that enables Two Factor Authentication (2FA) in applications using authenticator apps like Google Authenticator. It provides tools to generate and manage time-based one-time passwords (TOTP), simplifying secure user authentication. The package supports multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, ensuring cross-platform consistency. With straightforward integration via the command `flutter pub add flutter_2fa`, developers can enhance app security with minimal setup. It's ideal for apps requiring strong user verification without relying solely on passwords.
