Discover in Firebase the method by which the user is connected, whether it be through Google, Facebook,

Can anyone help me identify the method through which a user connected in firebase (such as Facebook, Google, email...)? I am looking to retrieve this information using JavaScript.

https://i.sstatic.net/9jL4o.png Below is a breakdown of popular authentication providers:

                    switch (user.providerData[0].providerId) {
                        case "facebook.com":
                            console.log("User logged in with Facebook");
                            break;
                        case "google.com":
                            console.log("User logged in with Google");
                            break;
                        case "password":
                            console.log("User used email and password to login");
                            break;
                        case "twitter.com":
                            console.log("User used Twitter for login");
                            break;
                        case "github.com":
                            console.log("User utilized GitHub for login");
                            break;
                        case "apple.com":
                            console.log("User authenticated via Apple provider");
                            break;
                        case "yahoo.com":
                            console.log("User chose Yahoo as the login method");
                            break;
                        case "hotmail.com":
                            console.log("User opted for Hotmail for authentication");
                            break;
                        default:
                            console.log("User signed in with an unknown provider")
                    }
                });

If you're in search of the providerId, you've come to the right place.

You can find this information in Firebase auth's official documentation (https://firebase.google.com/docs/auth/web/manage-users):

var user = firebase.auth().currentUser;

if (user != null) {
  user.providerData.forEach(function (profile) {
    console.log("Sign-in provider: " + profile.providerId);
    console.log("  Provider-specific UID: " + profile.uid);
    console.log("  Name: " + profile.displayName);
    console.log("  Email: " + profile.email);
    console.log("  Photo URL: " + profile.photoURL);
  });
}
