Service Account Key

Get your service account key from IAM Open google IAM

WARNING (Password hashes of users)

Firebase API also returns the passwordSalt and passwordHash hashed by the Firebase Auth backend for password users if the user/service account used to generate the request OAuth access token has the firebaseauth.configs.getHashConfig permission. Otherwise the passwordHash and passwordSalt will not be set. Open official firebase docs

WARNING (restoration of subcollections)

I recommend using only the top collection level in the collections parameter. Because you can get shadow document by restoring a subcollection in a non-existent document. To a full database cleanup, including shadow documents, use the command in firebase tools

    firebase firestore:delete -r
