Quickstart-android: This app is not authorized to use Firebase Authentication. Please verifythat the correct package name and SHA-1 are configured in the Firebase Console.

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.
