Why FCM setup in Firebase? - Purpose & Use Cases

The Big Idea

What if you could notify millions of users instantly with just one setup?

The Scenario

Imagine you want to send important messages to your app users one by one, typing each message and sending it manually every time.

The Problem

This manual way is slow, tiring, and easy to forget or make mistakes. You might miss some users or send wrong messages, causing confusion.

The Solution

FCM setup lets you automate sending messages to many users at once, reliably and quickly, without typing each message manually.

FCM setup automates and simplifies sending notifications.

This helps apps communicate quickly and reliably with users.
