Multiple firebase accounts created on Google login












0















Our (Electron) app is backed by firebase for authentication, where we have two authentication methods enabled; namely: Email and Google Accounts.



When authenticating with Google, we open a non-Electron browser window and provide the required redirect_uri. The http service is provided by our Electron app which is listening for Google's authentication code. Once the code is received, we make a request for the authentication token, and use it to further generate credentials required to login to our firebase project.



Everything during our testing worked correctly, however, we're seeing an issue where a small number of new logins will create multiple accounts in firebase, all with their own unique uid.



Additional notes:




  • Firebase project is setup to allow only a single account per e-mail address

  • Firebase version is 5.4.2


Login function



Once we retrieve the token, the following function is responsible for logging the user in.



public async googleLogin(credentials) {
try {
const googleCred = firebase.auth.GoogleAuthProvider.credential(credentials.id_token);
await firebase.auth().signInAndRetrieveDataWithCredential(googleCred);
// auth successful, firebase.auth().onAuthStateChanged() will fire
} catch (err) {
// authentication error.
}
}


The number of accounts created per Google address vary (so far, we've seen from 2 to 7 different uids being created for a single Google account).



Unsure what may be causing this from our end, but if anyone has any ideas, it would be greatly appreciated.



Note: I have also written to Firebase support, and will update the question (or post an answer) when we do manage to resolve this.
