Firebase auth was working fine, the debug build suddenly started failing without any change of code, logging the folloing message

D/PhoneAuthActivity( 7392): signInWithCredential:failure:com.google.firebase.auth.FirebaseAuthException: This app is not authorized to use Firebase Authentication. Please verifythat the correct package name and SHA-1 are configured in the Firebase Console. [ App validation failed ].

The only notable activity inbetween a successful login and failure is android studio upgrade.

@ishandutta2007 the error message tells you exactly what is going on. At some point in your "android studio upgrade" you likely deleted your android debug keystore which means your builds have a new SHA1 . Just follow the steps to add your app to your Firebase project again and this should be fixed.

'./gradlew clean' -> inside root folder
Then re-buid the project

I was using a Window computer, now i switched to Mac so i copied the whole app folder. But the problem is i get the error:

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. [ App validation failed ]

I signed it also. i got the SHA-1 code and added to google.

signingConfigs{
release{
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
storePassword keystoreProperties['storePassword']
}
}

Make sure you are running your app on a Physical Device. This error mostly occurs when you are running your app in an emulator.

Just open terminal enter this command cd android && gradlew signingReport you'll get multiple information in which copy Task :app:signingReport > debugUnitTest > SHA1 and add to firebase SHA certificate fingerprints.
After all re-build your app. Then it'll work.

Hi, someone was able to fix the error. I tried the following:

1. Get SHA1 from the debug keystore and add the firebase project settings.
2. Get SHA1 Released on Play App Signing
3. Link the application with the Play Console.

All those options didn't work for me, I removed the app and it didn't work either.

The login with Phone Number does not work, but the Facebook one does.

The first time I thought I had managed to fix the error, I tried it in Internal Tests and it worked fine, I uploaded it to production, and then it stopped working again.

I'm really desperate and I don't know what to do

[adamGT]

I've had this same issue for days. After trying every possible solution I found out my firebase-auth dependency version was (19.3.1) and when I change it to the latest i.e (20.0.3) it worked fine.
I hope this helps
