This app is not authorized to use Firebase Authentication on USB Debugging

Question

I have done exactly what this question's answer says: https://stackoverflow.com/a/53513327/10021456

I copied both my App signing certificate SHA-1 and my Upload certificate SHA-1 to my Firebase SHA certificate fingerprints

I am just trying to run a Flutter app on my mobile phone, through USB debugging. So it is not a download from the app store or anything. Right at the start I get this error when I try to create a new user using Phone Number Authentication

Any idea on what I might be missing?

(I use Flutter for my app)

Information:

Example phone numbers work fine. But normal/unregistered phone numbers give the error.

This is the error message:

This app is not authorized to use Firebase Authentication.Please verify that the correct package name and SHA-1 are configured in the Firebase Console

What is the error message and have you tried with example phone numbers? (these can be configured on firebase console) — Chenna Reddy, Sep 24 '19 at 17:35
Did you also added debug keystore sha1 to firebase? App signing certificate sounds like the release keystore — xsheru, Sep 24 '19 at 19:57
@ChennaReddy I updated my question with the details you asked for — Paul Kruger, Sep 25 '19 at 06:32
@xSHERU I don't understand what you mean with `Did you also added debug keystore sha1 to firebase?`. Where do I get a debug key? — Paul Kruger, Sep 25 '19 at 06:34
I think the directory I shared is same @PaulKruger i will confirm it once i reach home this evening. Meanwhile check if I am correct — xsheru, Sep 26 '19 at 07:18

I have the same problem as you. I don't know about the windows. But this solution for Linux users.

Go to Project folder cd android then open the terminal ( Ctrl + Alt + T )

Run this comment ./gradlew signingReport

You will get the SHA1 and SHA256 for your project. Copy that SHA1 and SHA256, Paste it in Google firebase.

That's worked for me. If you face any problem contact me.

Hey based on our conversation, probably you haven’t added debug keystore SHA-1 to firebase console app configuration.

If you are using Android Studio on Windows then it will be located at

C:\Users\USERNAME\.android\debug.keystore

In case you are using Android Studio on Mac then it will be located at

/Users/USERNAME/.android/debug.keystore

In case you don’t find the file in said directory then just use android studio to install app on your phone. It will be generated automatically.

As you have already added release keystore SHA-1, I think you know how to get SHA-1 from keystore. You can also use Keystore Explorer tool for it.

UPDATE 1: Since you are using android studio now to build your app it became easy.

In android studio on right hand side you will see Gradle Tab. Open it.
Open (root) in this tab.
Open Tasks -> android
Click on ‘signingReport’
You will find the signing report at the bottom and scroll through it you will see SHA1 just copy it to your firebase project settings.

Hope this will solve your issue.

UPDATE 2: You can get SHA1 of that keystore by other means as well.

Download this tool and open your debug keystore file using this application. Get the SHA1 from there and add it to your Firebase Configuration. http://keystore-explorer.org/downloads.html

I tried building the app with android studio, that doesn't work. I do have a debug.keystore file on my mac at that location, but what do I do with it? — Paul Kruger, Oct 01 '19 at 15:45
I don't see a gradle tab, would you have this in a Flutter app? — Paul Kruger, Oct 01 '19 at 16:44
