i want to ask if there is some permissions required for phone authentication in Firebase flutter to work on android real devices like after releasing the app ? When i'm building the app on real device it work perfectly but when i release the app it doesn't work ,ths is the error i got 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 ex: like we know for the internet permission we put inside the android_manifest for the app to work on internet

Hey all of you thnks for the answer you provide,the mistake was; i release the app and continue to use the same debug SHA-1 key while i was supposed to use the release SHA-1 key , so to anyone who will meet this kind of problem should first change the release key in the Firestore console before attempting to make any other changes

So, if you want to use firebase for database services only then there is no need to provide SHA 1 key and package name, But since you are using firebase authentication service you have to provide all these things so that firebase authentication works perfectly.

for Package name follow :- ProjectRoot ->android ->src ->main -> Android manifest

enter image description here

And for Generating SHA1 key link

After getting both these things Go to Project Setting in Firebase Console inside project scroll a bit you can see package name and sha1 key enter those and you are ready to go.

  • I did all of these things, I checked the package name and the SHA-1 key to see if they are the same, which I found the same so I don't know the problem – rutayisire willy Aug 14 '20 at 06:47

Since you are using firebase, add both SHA-1 and SHA-256 certificate in firebase console settings
