Firebase Authentication provides backend services and SDKs to add user sign-in to your app with multiple auth providers. Reach for this skill when you need user management, secure sign-up/login flows, or to enforce Firestore/Realtime Database security rules based on authenticated users. It handles uid generation, user properties, and integrates seamlessly with Firebase's security ecosystem.
- Configure Firebase auth providers (email, phone, OAuth) and manage user identity
- Set up Firestore/Realtime Database security rules gated by authenticated user uid
- Implement sign-in, sign-out, and account management flows in your app
- Integrate Firebase CLI for local testing and production deployment of auth rules
