iOS App in Python with Kivy - Part 8: Login Screen with Firebase Authentication

Part 8 of the Friendly Fitness iOS app in Python with Kivy tutorial

👇 LINKS AND INFO! 👇

In this video I allow users to sign up using their email and password by using Google Firebase's authentication feature. It's a super nice feature that handles a lot of things for you. I use the unique account id associated with an email/password combo to contain the data for each user in the real-time database. Next video will cover using the "refresh token" that Firebase authentication supplies to keep users logged in even when closing the app.

When writing your own app with Firebase, please do not share the web API key. It is meant to be secure and I'm only showing mine for the purpose of this tutorial. It will be taken down when the tutorial is finished.

Get the code on my github:

And follow along with some of my work at:

Great video Erik. Your channel really deserves a lot more subscribers!
Just leave a note here for someone who wants to use Kivy UrlRequest instead in this part. UrlRequest strongly depends on Kivy and seems to only work in a class that inherits Kivy classes. So you will either want to run it inside a Kivy class, or let MyFireBase inherit a Kivy Widget. To pass the data in a POST you also need to convert it into a json format first, with something like json.dumps.

Hi can you tell me how to ask for storage permission?
I mean when the app is opened then it should automatically ask for storage permission.

Thanks for all the videos 👍

Hey man, I'm getting ADMIN_ONLY_OPERATION as my 400 error messge instead of INVALID_EMAIL... and it persists for invalid password etc. Where should I look?

Bro, thank you for your video,

At the end of your video, in firebase rules, you used write and read if only localId = auth.uid, but the thing is you already mentioned read: true and write: true, so no matter what is your status, it will read and write the data, I tried to follow you and change read and write to false, there where only I am getting an error, one more thing is if I am having localIds in database inside a key inside the database, could this rule also work ?!

also any idea regarding how to use the same thing with pyrebase because pyrebase looks more easier although its roots are coming from requests as the same steps you mentioned.

[pbh]

Why your don't use helper libraries like pyrebase or python-firebase ???

Has anyone been able to break up the below line of kivylang code from loginscreen.kv:

rgb: if self.state == 'normal' else

I've tried several alternatives with "on_state" and "\", none of which seem to work.
