In this video, we create a flutter application and implement phone authentication, which allows your users to sign up and sign in using only their phone and an OTP code. We also added an additional (optional) step where you can sign up users and store their information to the firestore database, for example their name. Users can then sign up, sign in, and logout, all without any password and only using phone authentication.

Let me know in the comments below what else we should do with Flutter in our upcoming videos.

PLEASE NOTE:

These are also one important step to follow which have been added since I made the video:

In the Google Cloud Console, enable the Android DeviceCheck API for your project. The default Firebase API Key will be used, and needs to be allowed to access the DeviceCheck API. https://console.cloud.google.com/apis/library/androidcheck.googleapis.com
