Firebase Authentication in App Inventor | Sign In | Sign Up | Private Node in 2020

Firebase is not secure enough? No, the App developer makes it insecure. In fact, a lot of online instructions, and even my guide for newbies to Firebase will ignore Firebase security rules so that you can easily set up Firebase for your application and get acquainted with it. And therefore, any user who knows the Firebase Database Url can read/write to all data on Firebase. Firebase itself also warns the developers (via email) when we set up something less secure so don't ignore that warning. This tutorial has 4 sections: 1. Get Info from Firebase Realtime Database 2. Set up FirebaseDB component & FirebaseAuth Extension 3. Upgrade Firebase RealtimeDatabase Rules 4. App Inventor Test App Design & Block This tutorial will help you to set up rules on Firebase Realtime Database, properties of related components in App Inventor, simple design, and blocks to make a connection between your App & Firebase secure.
