About Firebase Auth

Firebase Auth is Google's managed authentication service for web and mobile apps.

Firebase Auth handles user identity for web, mobile-web, and Node.js applications, supporting sign-in methods such as email/password, phone numbers, and federated providers like Google and other OAuth-based services. It manages token issuance, session persistence, and user account lifecycle, so developers don't have to build or maintain their own auth backend. It's aimed at app developers who want to add user authentication without running their own identity infrastructure.

Where to start

Initialize a Firebase project and app via the Firebase console, then import the auth module from the Firebase JS SDK using 'firebase/auth' to access functions like createUserWithEmailAndPassword, signInWithEmailAndPassword, and onAuthStateChanged.
