[Guide] How to use Firebase Authentication :google: :firebase: on :kodular:

Hello Koders! In this guide, I’m going to explain how to use the “Firebase Authentication” component in yoour apps and it’s utilities. I hope you find it useful :wink:

What is Firebase Authentication?

Firebase Authentication is a :google: :firebase: service that allow your users to log in and sing up into your app. Basically, you can have a login service for free with this componet/service.
You don’t need any extension, because :kodular: already have it.

How to add it?

It’s simple. Go to the :google: section on your designer and drop the component to your screen.

Configure it…

Firebase Configurations

1. Add your APP to Firebase

First, go to your :firebase: console. Select your APP project. (If you don’t have it, create one. Remember not to enable Google Analytics)
To create your APP, click on the Android Logo :android:, and complete ALL THE STEPS. The SHA-1 key is in your Account Settings :gear: at the top right of your creator.
Then, upload your ==google-services.json== file to your app assets

2. Enable login methods

Go to AUTH settings / Sign-in Methods and enable Google, EMAIL and PHONE methods. (You can enable only what you want to use on your app)

Thanks!! :blue_heart::blush:

I was actually complimenting you for making this guide because some people don’t read the docs. This way when (or if) they search the forum your guide will come up.

I’m not sure why you took my post the wrong way.

Hi,
I was reading your guide and looking for a way to validate the user phone number on signup. But in the blocks only i saw, Verify Phone Code but no blocks on when to send the code and validate that code against what input?

Am i missing something here?

Did anyone tried validating the phone number by sending otp using firebase to the said number and then validating whether the code is correct or not?

To send the code, to will have to use this block @Meghraj_Singh
