What is Firebase Authentication?

Firebase Authentication is a backend service provided by Google Firebase that simplifies the process of authenticating users in our applications. It offers several authentication methods, including email and password, phone number, Google, Facebook, Twitter, GitHub and more. With Firebase Authentication, we can securely authenticate users and manage user identities in our application....

How Firebase Authentication Works?

Firebase Authentication works by providing a set of client-side SDKs (Software Development Kits) for popular platforms such as Android, iOS and the web. These SDKs handle the authentication process on the client side, communicating securely with the Firebase backend services. When a user attempts to sign in to our application, Firebase Authentication SDK initiates the authentication process by requesting credentials from the user. The credentials are then securely transmitted to Firebase servers, where they are verified against the configured authentication provider (e.g., Firebase Authentication server, Google, Facebook, etc). Once the user’s credentials are verified, Firebase Authentication generates a unique authentication token, which is sent back to the client application. This token serves as proof of the user’s identity and can be used to access Firebase services and resources securely....
