Firebase Auth Basics

This walks you through setting up Firebase Authentication with email/password, Google Sign In, anonymous auth, and other providers. You get the full flow: enabling providers via CLI or console (including the critical deploy step for OAuth client generation), wiring up the client SDKs for web, Flutter, and Android, and securing your Firestore or Storage data with auth rules. The documentation is clear about the token lifecycle and user properties you'll be working with. If you're building anything that needs user accounts or gated data access, this covers the standard Firebase auth setup without the guesswork. The references are split by platform, which keeps things focused when you're actually implementing.
