Ideal for game projects requiring user authentication, such as multiplayer games, leaderboards, or social interaction systems. It saves developers weeks of backend infrastructure work, allowing them to focus on building gameplay and user experiences instead of worrying about complex server architecture and security concerns. The plugin implements various common authentication flows such as email/password authentication, password reset, token management, and Firebase password updates.

Key Features :

1. Email and Password Registrations :

   • Easily create new user accounts by registering with a user’s email and password directly in-game.

   • Verify and manage new users securely using the Firebase backend.

2. Secure Login with Firebase Authentication :

   • Allow existing users to log in securely using their email and password credentials.

   • Utilize Firebase's real-time token-based security system to ensure safe and scalable authentication.

3. Change Password Functionality :

   • Implement password-change flows directly from the client side.

   • Users can update their password securely through Firebase, ensuring safe password storage without developer-side handling.

4. Reset Password Support :

   • Integrated with Firebase’s password reset API, allowing users to request a reset password email whenever needed.

   • Ensure compliance with best practices for handling and resetting user credentials.

5. Simple Token Management :

   • Manage Firebase ID tokens easily and maintain user session authenticity during key operations.

   • Automatically manage token expiration and refresh events to keep the user logged in across play sessions.

6. Password Validation & Strength Metrics :

   • Support for Firebase’s password complexity rules, ensuring that users select safe credentials during registration.

   • Easily handle Firebase’s error responses for weak passwords and other password-related issues.

7. Scalable and Cloud-Based :

   • Utilize the power of Google Cloud's Firebase to automatically handle user scalability—whether a few players or millions.

   • No need to worry about server maintenance or manual scaling; Firebase does the heavy lifting.

8. Comprehensive Error Handling :

   • Detailed error responses direct from Firebase, allowing precise issue logging and graceful failure handling within your game’s UI.

   • Handles common authentication errors such as invalid email, incorrect password, and user not found, making it easier to manage situations effectively.

9. User Session Persistence :

   • Keep users logged in across gameplay sessions by saving their valid tokens and user states across app restarts.

10. Blueprint and C++ Integration :

    • Full Blueprint exposure with highly customizable nodes for common Firebase authentication actions like login, registration, and password management.

    • Written in efficient and scalable C++ that can be expanded or customized to meet your game’s specific requirements.

11. Developer Friendly :

    • Easy to use, with well-documented functions for common authentication tasks.

    • Firebase Login System is made to interface smoothly with Unreal's architecture and be as lightweight as possible, allowing developers to integrate full authentication flows within minutes.

12. Enhanced Security :

    • Take full advantage of Firebase’s built-in security frameworks. All user credentials are securely stored and handled via Firebase, removing developer responsibility for sensitive information storage.

13. Cross-Platform :

    • Integrates seamlessly into multi-platform UE5 games, including PC, mobile (iOS, Android), and console platforms. Once implemented, it works with no additional modification.
