Implementing User Authentication – Secure Logins and Sign-Ups

Firebase Authentication:

• Firebase simplifies the process of adding user sign-up and login features to your app. It supports Google, Facebook, Twitter, and email/password authentication.

Security Considerations:

• Always use HTTPS to encrypt data sent between the app and servers.
• Use Token-based Authentication (JWT) to manage user sessions securely.

Session Management:

• SharedPreferences (Android) and UserDefaults (iOS) can store the user’s authentication token, allowing them to remain logged in across sessions.
