The document provides an overview of using Firebase for authentication and analytics, aimed at both beginners and advanced developers. It explains Firebase as a backend-as-a-service that consolidates various functionalities like analytics, database, and crash reporting into one platform, promoting ease of use and better insights. The architecture of Firebase authentication is outlined, emphasizing the importance of understanding the process for coding across different authentication providers.

1. AUTHENTICATION
WITH FIREBASE
S H A B A B K A R I M
A N D R O I D D E V E L O P E R
B R A C U N I V E R S I T Y

2. OBJECTIVE
Beginners:
• Project creation with Firebase
• Working with Firebase Auth.
• Some OOP concepts.
• Handling callbacks.
Advanced Devs:
• Working with Firebase Auth
• Powering up your app analytics.

3. SO WHAT IS
FIREBASE
AGAIN?

4. WHAT IS FIREBASE
• It is a Backend-as-a-Service or BaaS
• Everything from analytics, database to
crash reporting and testing in one
single platform.
• With the introduction of cloud
functions we can use it is a hosting
service too.

5. WHY USE FIREBASE
WHEN I HAVE A
PERFECTLY FINE
BACKEND AND
PROVIDER API
IMPLEMENTED?

6. CODE COMPARISON
WITHOUT FIREBASE WITH FIREBASE

7. ANALYTICS
• No more multiple dashboards for
multiple providers.
• User analysis and monitoring in one
place.
• Better insights.

8. ITS FREE, KINDA
• Good place to start if you don’t know how successful your app is going to be
• Has a pretty big limit for an initial app
• If your app reaches that limit that limit then you will be raining dollars with Admob.
$25/month won’t hurt.

9. CAN WE GET TO
THE CODING
PART NOW?

10. NOPE

11. FIREBASE ARCHITECTURE
• Firebase follows the same architecture for all authentication providers.
• If we understand the architecture then we can code for any authentication provider.

12. FIREBASE ARCHITECTURE
• First connect to the provider API
• On successfully logging to the
provider get the user credential token
• Pass the token to firebase
• Firebase registers the user and calls a
success callback.

13. LETS GET
CODING!!

14. CRITICAL CASES
• What if my Facebook account uses xyz@gmail.com and also my Gmail account uses
xyz@gmail.com ?
• Anonymous email password is not encrypted.

15. QUESTIONS??

16. THANK YOU!!
