Firebase projects are Google Cloud Platform projects that use Firebase services. This means that:
- Billing and permissions for projects are shared across consoles.
- Unique identifiers for a project (like Project ID) are shared across consoles.
- Projects that appear in the Firebase console also appear in the Google Cloud Platform and Google APIs consoles.
- Deleting a project deletes it across all consoles.
Projects let you share users, data, and analytics across platforms (Android, iOS, and web) so your users have the same experience whatever device they're on. Every app using Firebase is connected to a Firebase project so that you can manage all versions of your app through the Firebase console.
