Q: Troubleshooting Firebase Authentication Setup I'm taking the Firebase Authentication service for a trial run. And having some initial Qs: 


*

*Howto use the accountChooser ? 

*Howto enable Twitter & Github access ? ie, it's not clear to me, where we get the


*

*API key

*API secret

*Callback URL for Twitter or for an example? 


*From where do I get the correct apiKey and authDomain? 


fig.1
var config = {
  apiKey: "<key-from-google-console>", 
  authDomain: "<my-app>.firebaseapp.com" 
};

firebase.initializeApp(config);

I got my current values from the Google API Manager Creds Dashboard. But when I press the Sign in with Google button, I get the error: 
fig.2 (on firebase-ui-auth.js:206)
Internal error: 
{
  "error": {
    "errors": [
      {
        "domain": "global",
        "reason": "invalid",
        "message": "CONFIGURATION_NOT_FOUND"
      }
    ],
    "code": 400,
    "message": "CONFIGURATION_NOT_FOUND"
  }
}


A: Figured this one out. I was using an apiKey: "<key-from-google-console>", from my existing, external google account. The easiest thing to do was to use the apiKey from my new Firebase account. 
There's probably a way to use previous / existing Google apiKeys. I just haven't figured that out yet. 
Hth.

A: I had to enable authentication for the sign in methods I was using in the Firebase Console

A: I'm creating registration form and trying to connect to firebase but nothing showing up in firebase authentication and when I click on register button I get this line of output, I have enabled password/email in sign-in user as well.
An internal error has occurred. [ CONFIGURATION_NOT_FOUND ]
