firebase-auth-basics

Set up Firebase Authentication with multiple identity providers and secure data access rules.

• Supports email/password, phone number, anonymous, federated providers (Google, Facebook, Twitter, GitHub, Microsoft, Apple), and custom auth integration
• Each authenticated user receives a unique ID and JWT-based tokens (short-lived ID tokens and long-lived refresh tokens) for accessing Firebase services
• Enable providers via CLI for Google Sign In, anonymous, and email/password; use Firebase Console for additional federated providers
• Secure Firestore and Cloud Storage using request.auth in security rules to control data access based on user identity
