FirebaseUI Auth - Facebook Login error : Unsuccessful debug_token response from Facebook

Question

I\'m trying to integrate FirebaseUI Auth library. Google sign-in and Email sign-in are working fine but I have a problem setting up Facebook Login. This is my code:

Answer 1

make sure this is correct with facebook dev page

Answer 2

I didn't have the switch toggled saying "Yes" to "Is this a native or desktop app". I then re-entered the app secret in Firebase and made sure to add the OAuth Redirect URI to the Facebook app.

Answer 3

You need to check the both: App secret and App ID from the Facebook developers page and Firebase Authentication (Facebook Provider), because Firebase by default has his own ids
