SHA1 key for Firebase (!important)

Google auth requires a SHA1 key to work. You need to add the SHA1 key to the Firebase console.

• To generate a certificate run cd android && ./gradlew signingReport. This generates two variant keys. You have to copy both 'SHA1' and 'SHA-256' keys that belong to the 'debugAndroidTest' variant key option. Then, you can add those keys to the 'SHA certificate fingerprints' on your app in Firebase console.
  • Go to the Firebase console.
  • Select your project.
  • Go to Project settings.
  • In the Your apps card, select the Android app.
  • In the SHA certificate fingerprints section, click Add fingerprint.
• in prod after releasing the app, you have to add the SHA1 key of the release key to the Firebase console.
• To get the SHA1 key for the release key:
  • Run the following command: keytool -list -v -keystore <PATH_TO_YOUR_RELEASE_KEY> -alias <ALIAS_NAME> -storepass <STORE_PASSWORD> -keypass <KEY_PASSWORD>
  • Replace the placeholders with the actual values.
  • You will find the SHA1 and SHA-256 keys in the output.
• if signing is managed by google play, you can find the SHA1 key in the google play console.
  • Go to the Google Play Console.
  • Select your app.
  • Go to Release > Setup > App Integrity.
  • Copy the SHA-1 certificate fingerprint from the App signing certificate section.
  • Add the SHA-1 certificate fingerprint to the Firebase project.

Firebase auth service account for backend

1. Go to Firebase Console -> Project Settings -> Service Accounts.
2. Click on 'Generate new private key'.
