Firebase Authentication
Firebase Authentication is a backend service provided by Google Firebase that handles user authentication for web and mobile applications. It supports multiple authentication methods including email/password, phone number, and federated identity providers like Google, Facebook, and Twitter. The service manages user sessions, tokens, and integrates seamlessly with other Firebase services and custom backends.
Developers should use Firebase Authentication when building applications that require secure user sign-up and login without managing complex authentication infrastructure. It's ideal for rapid prototyping, mobile apps, and web applications where developer productivity and security are priorities, such as in startups or projects with limited backend resources. The service reduces development time by providing pre-built UI components and SDKs for various platforms.
