Firebase: This domain is not authorized
FirebaseMobileOauthFirebase Problem Overview
I imported Firebase JS v3 API and used to initialize Firebase using:
firebase.initializeApp(config);
However the app failed to load correctly via web browser on localhost, resulting in the following error:
> Error: This domain is not authorized for OAuth operations for your > Firebase project. Edit the list of authorized domains from the > Firebase console. > > firebase.js:71:1333
Firebase Solutions
Solution 1 - Firebase
I solved the problem by adding the localhost domain to OAuth redirect domains (within SETUP SIGN IN METHOD on the Auth tab of Firebase console).
Solution 2 - Firebase
> in firebase console Auth --> Authorised domains
> must equal (in Google cloud console -- > API & Services --> credentials ) :
> must equal (in api config) :
Solution 3 - Firebase
Solution which worked for me after trying out all the options on the listed above and on other sites regarding using FireBase oAuth was the following:
- login at https://console.cloud.google.com
- Go to APIs & Services > Credentials
Once here, locate API Key you are using in your app that connects to FireBase
- Now add your custom domain to HTTP Referrers
For android or ios or having your application on all three mediums, you will need to create API keys per medium.
Solution 4 - Firebase
Make sure the "authDomain" in your config matches the one in your firebase console. If you're running the app on localhost, make sure it's set to localhost and localhost exists on your firebase console.
Auth -> Sign In Method -> OAuth redirect domains
var config = {
apiKey: "...",
authDomain: "...", // this should match the one on your firebase console
databaseURL: "...",
storageBucket: "",
};
firebase.initializeApp(config);

For me the source of the error was that the domain was not added in the firebase console.
Here is an image in the firebase console to add the custom domain for your website:

Problem Authorised domain Firebase Locahost OAUTH2
If you are using Google Chrome you can see a problem with the Identity Toolkit API DISABLE. You need to enabled this API on the google cloud project to get OAUTH servcies in Firebase project.
Solution 7 - Firebase
For those having this issue in Heroku:
Make sure you keep the authDomain property with the same value you got from Firebase.
DO NOT change this to the current Heroku domain.
Solution 8 - Firebase
None of the above answers worked for me, as I already had localhost in Authorized domains list. For me the problem was incorrect API key, I must have somehow deleted one of the characters from it. I got a more descriptive (or rather - not misleading) error message when I changed to signInWithPopup to signInWithRedirect. Possibly the same problem might happen when the API key is expired.
Solution 9 - Firebase
Not really specific to Android, but check the address in your actionCodeSettings.
actionCodeSettings.url must be correct and whitelisted.
Solution 10 - Firebase
The important point is.. you must add the yourprojectid.firebaseapp.com domain to the authorized domains.. not your real domain name. That worked for me.
Solution 11 - Firebase
None of the above solutions worked for me but this did.
- Go to Google console Authentication tab > Sign In Method > Authorized Domains
- Add
127.0.0.1
localhost was already in my Authorized Domains but in my case I needed to add 127.0.0.1 as well
