Firebase OTP working fine on debug apk but not release apk

I am using flutter and firebase OTP. The SMS is received while running the debug APK of my app. However, I am getting this message while running the release APK using the command flutter run --release.

This is the returned 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. [ A safety_net_token was passed, but no matching SHA-256 was registered in the Firebase console. Please make sure that this application’s packageName/SHA256 pair is registered in the Firebase Console. ]

Kindly note that I am running this app directly on my phone and not by installing it from google play.

I tried the following on firebase console:

  1. Debug keys
  2. Release Keys
  3. Google Play signing and upload keys certificates.
  4. Also my google-services.json is up-to-date.
  5. Flutter clean and pub get before running in order to make sure that the changes will occur.

I tried all the solutions presented by similar questions such as adding an email in firebase, adding google play keys, etc. and unfortunately none of them worked.

Update: Solved, the problem was wrong naming inside the manifest file as the error message stated:
Please make sure that this application’s "packageName/SHA256" pair is registered in the Firebase Console. Usually, it is the sha1 or sha256 keys, however this time it was the package name.

You will have to add 4 SHA keys.

Run cd android, then run ./gradlew signingReport

I assume you have already added debug SHA keys, because you can send OTP on debug builds.

Scroll up on the output of signingReport and look for Variant: release, copy SHA1 and SHA-256 from here and add them into firebase app, in addition to the debug keys.

Hope this helps!

You need to add SHA Keys in firebase console, to get SHA KEY

  • Open Android Studio
  • Open Project
  • Reveal android folder
  • Right click "gradlew" file and select Open in Terminal
  • Go to the terminal view and paste: gradlew signingReport

You will find the SHA-1 fingerprint in the "Gradle Console"

Add this SHA-1 fingerprint in firebase console and test again

You have to generate SHA-1 for relase build and add it to the firebase console for the same project that you have registered.
