Firebase Authentication
Firebase Authentication is a backend service provided by Google's Firebase platform that enables developers to easily add user authentication to their web and mobile applications. It supports multiple authentication methods, including email/password, phone number, and social logins (e.g., Google, Facebook, Twitter), and handles secure user management, session persistence, and identity verification. It integrates seamlessly with other Firebase services and third-party identity providers, reducing the need for custom server-side code.
Developers should use Firebase Authentication when building applications that require quick and secure user sign-up and sign-in, especially for prototypes, MVPs, or projects where minimizing backend development time is crucial. It is ideal for mobile apps (iOS, Android) and web apps that need social login integration, multi-factor authentication, or real-time user data synchronization with Firebase services like Firestore or Realtime Database. Use it in scenarios where scalability, security compliance (e.g., GDPR), and ease of implementation are priorities over full custom control.
