Firebase is a unified application development platform to create, deploy, and monitor web and mobile experiences. It unites common product functions in a single platform, freeing engineers to create functionality and user experience rather than having to create the infrastructure.

This course is a comprehensive introduction to the Firebase 9 SDK through hands-on development of a web application. You’ll start with basic concepts and functions like authentication, database, and Cloud Storage with Firestore. You’ll then learn Cloud Functions for Firebase, environment variables, Security Rules, and hosting capabilities before deploying an application using the command line interface (CLI). At each step, you’ll get hands-on exercises to modify the code, see real-time output in your browser, and finish with an assessment.

By the end of this course, you’ll have all the tools you need to build and deploy a web application with the Firebase 9 SDK—the latest version of Firebase.

# Re-authenticate users
Sometimes, we may need to reauthenticate our application users before they perform security-sensitive actions, such as deleting an account, changing their primary email, or changing their passwords. These actions fail with an error if the user performing them signed in a long time ago. When this happens, we need to reauthenticate the user by requesting new sign-in credentials from either the user or the sign-in provider.

The Firebase Authentication SDK provides the `reauthenticateWithCredential` function, which receives the new user credentials to handle such cases:
