Now that we’ve covered the possible causes, let’s dive into the debugging process. Follow these steps to identify and fix the issue:
- Check your Facebook app settings: Ensure that your Facebook app ID and app secret are correct and properly configured. Double-check that your app is set up correctly in the Facebook Developer Dashboard.
- Verify your Firebase config: Make sure your Firebase config is correct and that you’re using the correct Firebase project and app ID. Check your Firebase console to ensure that the Facebook provider is enabled.
- Inspect your redirect URI: Verify that the redirect URI in your Firebase config matches the one specified in your Facebook app settings.

Resolving the Error Code 190
Now that we’ve identified the issue, let’s resolve it! Here are some solutions to common problems:
Invalid or expired Facebook access token
If you’re using an invalid or expired Facebook access token, you’ll need to refresh it. Here’s how:
// Get a new Facebook access token const newToken = await firebase.auth().getAuth().currentUser.getIdToken(true); // Use the new token to authenticate with Firebase const credential = firebase.auth.FacebookAuthProvider.credential(newToken); await firebase.auth().signInWithCredential(credential);
Incorrect app ID or app secret
If your app ID or app secret is incorrect, you’ll need to update them in your Firebase config and Facebook app settings. Make sure to use the correct values and update your code accordingly.
Mismatched Redirect URI
If your redirect URI is incorrect, update it in your Firebase config and Facebook app settings to match the correct value.
Invalid permissions or scopes
If your permissions or scopes are incorrect, update them in your Facebook app settings and Firebase config to match the correct values.
Common Pitfalls to Avoid
When working with Firebase Auth and Facebook token authentication, there are some common pitfalls to avoid:
- Don’t hardcode your Facebook app ID and app secret: Instead, use environment variables or a secure storage solution to store your sensitive app credentials.
- Don’t use an expired or invalid Facebook access token: Always refresh your token when it’s close to expiring or has expired.
- Don’t mismatch your redirect URI: Ensure that your redirect URI in your Firebase config matches the one specified in your Facebook app settings.
