Multiple firebase accounts created on Google login

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.

          Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

          Image
          28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

          Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

          Image
          up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form? I know that for Druids, it’s not an instant kill anymore, but is this the case for polymorph as well? dnd-5e spells polymorph errata share | improve this question edited 18 hours ago

          A Topological Invariant for $pi_3(U(n))$

          Image
          3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
