Firebase auth/operation-not-allowed for google 登录

Question

In React native App

I'm trying to authenticate google signIn using firebase.

In my firebase console > Authentication > signIn Method, I've enabled the google and saved it. Click here to view image.

But when I try to login It throws me an error saying that auth/operation-not-allowed

import Auth, { firebase } from '@react-native-firebase/auth';
import { GoogleSignin } from "@react-native-community/google-signin";

const {idToken} = await GoogleSignin.signIn();
const googleCredential = Auth.GoogleAuthProvider.credential(idToken);
return await Auth().signInWithCredential(credential);

And I have got error like

Error: [auth/operation-not-allowed] The given sign-in provider is disabled for this Firebase project. Enable it in the Firebase console, under the sign-in method tab of the Auth section. [ The identity provider configuration is disabled. ]
NativeFirebaseError: [auth/operation-not-allowed] The given sign-in provider is disabled for this Firebase project. Enable it in the Firebase console, under the sign-in method tab of the Auth section. [ The identity provider configuration is disabled. ]

Answer 1

It looks like you haven't enabled the Google sign in method in your firebase console. To solve the issue do the following:

1. Enter to the firebase console ( https://console.firebase.google.com/ ).
2. Select your project.
3. On the right side of the screen you'll see a panel, click where it says "Authentication".
4. Once you've entered to the Authentication menu, go to Sign-in method.
5. After that look for the google access provider in the list that appears below the header and click on it.
6. Then click on the enable button.

It is probable that you'll have to configure a secure project ID (you'll see a dropdown below the enable button). What you have to do is, enter the android and/or ios client ID from your project, and hit save. This will tell firebase that it is secure to handle sign in operations with that client.
