I have a quite strange or somewhat understandable(?) problem.
My firebase project support 4 types of authentications: Google, Apple, Facebook and anonymous.
I created 2 accounts. One has Google linked with facebook, the other one has apple only.
Then I link same facebook account that is already linked with google at apple account.
Firebase console shows no change but everytime I login into apple account, firebase returns google's UID.
I kinda understand that there are all linked into one account but I don't get why the apple's UID isn't removed and google's UID doesn't have apple provider from firebase console.
Another case:
Create 3 accounts: Google, Apple and Facebook separately.
Link all together into one. every time whichever I login into, firebase returns facebook's UID. (this is something that I completely unable to understand why.)
If it's normal, should I manage them manually on console or my project if I want to see it as one account on firebase console?
Edit:

So... I found that lack of knowledge about whatever I'm doing goes very wrong...
I used apple-signin-unity by lupidan from github and mixing various tutorials that I could found on google to expect it's working. :|
Firebase blocks linking multiple accounts that already registered.
Mine just dispose previous FirebaseAuth and overwrite new one.
that is why it looked like merging accounts that actually doesn't do anything right.
I should have been more careful before I ask question.
Edit:
What was actually going on is that there's no exception at apple login.
Others have exceptions by using "ContinueWith" function but apple doesn't.
by adding it, everything works okay.

Integrating facebook as an auth provider within firebase (already have a working gmail implementation). The below code works fine in Unity, the FB SDK prompts for token, enter it manually, token is passed to firebase, login can be seen in the console, the required scene is then loaded.
When this is built onto an android device the full behavior doesnt happen, the correct Facebook token is received either from fresh login or existing login, we enter the SignInWithFacebookOnFirebase function to log this account into firebase and nothing else happens, sits on the debug of ("your token is " + aToken);
Im pretty sure it has something to do with the async behaviour and maybe not awaiting the task but im not sure what, any suggestions would be great !

EDIT - So the problem is nothing to do with async, its the fact that the firebase credential is being persisted on the mobile device. I uncommented all of my already working google auth code below and we log into firebase with our facebook creds fine! So i need some method of clearing our this token when A) the user logs out and B) the user closes the app (Cleanly or uncleanly) Any help would be great !

this is solved, it was because i was checking that the firebase dependences existed in both these scripts and it was throwing an exception. I found this using the logcat logs \adb logcat -s Unity ActivityManager PackageManager dalvikvm DEBUG
I'm here to make a game with anonymous login with firebase auth, and a database with firebase real-time database, everything works smoothly except for firebase auth. The problem is I don't know why? the unity won't connect to firebase auth.
Installation
I already install the package like always database and auth
also for the firebase is like this
Script
here my login script :
//Firebase variables
[Header("Firebase")]
public DependencyStatus dependencyStatus;
public FirebaseAuth auth;
public FirebaseUser User;
public DatabaseReference DBreference;
public static FirebaseManager instance;
void Awake()
{
if (instance != null)
{
Destroy(gameObject);
}
else
{
DontDestroyOnLoad(gameObject);
instance = this;
}
FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread(task =>
{
dependencyStatus = task.Result;
if (dependencyStatus == DependencyStatus.Available)
{
InitializeFirebase();
}
else
{
Debug.LogError(
"Could not resolve all Firebase dependencies: " + dependency status);
}
});
}
public void InitializeFirebase()
{
auth = FirebaseAuth.DefaultInstance;
DBreference = FirebaseDatabase.DefaultInstance.RootReference;
auth.StateChanged += AuthStateChanged;
AuthStateChanged(this, null);
}
void AuthStateChanged(object sender, System.EventArgs eventArgs)
{
//This checks if the user (your local user) is the same as the one from the auth
if (auth.CurrentUser != User)
{
bool signedIn = User != auth.CurrentUser && auth.CurrentUser != null;
User = auth.CurrentUser;
if (signedIn)
{
Debug.Log("Signed in " + User.UserId + " " + User.DisplayName);
}
else
{
StartCoroutine(SignAnonymously());
}
}
}
//it does not directly log the user out but invalidates the auth
void OnDestroy()
{
auth.StateChanged -= AuthStateChanged;
auth = null;
}
public IEnumerator SignAnonymously()
{
var loginTask = auth.SignInAnonymouslyAsync();
yield return new WaitUntil(predicate: () => loginTask.IsCompleted);
if (loginTask.Exception != null)
{
//If there are errors handle them
Debug.LogWarning(message: $"Failed to register task with {loginTask.Exception}");
}
else
{
User = loginTask.Result;
Debug.LogFormat("User signed in successfully: {0} ({1})", User.DisplayName, User.UserId);
}
}
What I've tried
Check the google-service.json ( already same or updated )
already implement this https://firebase.googleblog.com/2020/08/firebase-compatibility-with-unity-20201.html due to a compatibility issue.
already changed continuewith to ContinueWithOnMainThread(task..
note: I'm using unity ver 2020.3.1f1 LTS
am I doing it wrong?
Try to replace your Coroutine method SignAnonymously with this async method:
public async void SignAnonymously()
{
await auth.SignInAnonymouslyAsync().ContinueWith(task => {
if (task.IsCanceled) {
Debug.LogError("SignInAnonymouslyAsync was canceled.");
return;
}
if (task.IsFaulted) {
Debug.LogError("SignInAnonymouslyAsync encountered an error: " + task.Exception);
return;
}
Firebase.Auth.FirebaseUser newUser = task.Result;
Debug.LogFormat("User signed in successfully: {0} ({1})",
newUser.DisplayName, newUser.UserId);
});
}
I think that the problem could be the lacking of ContinueWithat the end of your SignInAnonymouslyAsync, maybe you can use it on your Coroutine but I've never done it that way, tell me if it works ^^
I am developing an app in unity. I use the firebase google login method. basically google login is working and the user was listed in google firebase users log after login. the problem is, it is throwing an error. because of this can't fetch data from the firestore. even without firestore code, the app is showing the error
Got Error: DeveloperError Exception of type

Here is a working example of Google SignIn code w/ Firebase Authentication and GoogleSignIn libraries:
private void SignInWithGoogle(bool linkWithCurrentAnonUser)
{
GoogleSignIn.Configuration = new GoogleSignInConfiguration
{
RequestIdToken = true,
// Copy this value from the google-service.json file.
// oauth_client with type == 3
WebClientId = "[YOUR API CLIENT ID HERE].apps.googleusercontent.com"
};
Task<GoogleSignInUser> signIn = GoogleSignIn.DefaultInstance.SignIn();
TaskCompletionSource<FirebaseUser> signInCompleted = new TaskCompletionSource<FirebaseUser>();
signIn.ContinueWith(task =>
{
if (task.IsCanceled)
{
signInCompleted.SetCanceled();
}
else if (task.IsFaulted)
{
signInCompleted.SetException(task.Exception);
}
else
{
Credential credential = Firebase.Auth.GoogleAuthProvider.GetCredential(((Task<GoogleSignInUser>)task).Result.IdToken, null);
if (linkWithCurrentAnonUser)
{
mAuth.CurrentUser.LinkWithCredentialAsync(credential).ContinueWith(HandleLoginResult);
}
else
{
SignInWithCredential(credential);
}
}
});
}
The parameter is for signing in with intentions of linking the new google account with an anonymous user that is currently logged on. You can ignore those parts of the method if desired. Please note all of this is called after proper initialization of the Firebase Auth libraries.
Source: https://github.com/googlesamples/google-signin-unity
The readme page contains a step-by-step instructions for getting this setup for your environment. After following those and using the code above, you should have this working on both android and iOS.
Here is the SignInWithCredential method used in the code above:
private void SignInWithCredential(Credential credential)
{
if (mAuth != null)
{
mAuth.SignInWithCredentialAsync(credential).ContinueWith(HandleLoginResult);
}
}
`mAuth` is a reference to FirebaseAuth:
mAuth = Firebase.Auth.FirebaseAuth.DefaultInstance;
For someone asking for the HandleLoginResult from #DIGI Byte, here is the code, feel free to remove try/catch block for debug purpose:
private void HandleLoginResult(Task<FirebaseUser> task)
{
try
{
if (task.IsCanceled)
{
UnityEngine.Debug.LogError("SignInWithCredentialAsync was canceled.");
return;
}
if (task.IsFaulted)
{
UnityEngine.Debug.LogError("SignInWithCredentialAsync encountered an error: " + task.Exception.InnerException.Message);
return;
}
else
{
FirebaseUser newUser = task.Result;
UnityEngine.Debug.Log($"User signed in successfully: {newUser.DisplayName} ({newUser.UserId})");
}
}
catch (Exception e)
{
if (e != null)
{
UnityEngine.Debug.Log(e.InnerException.Message);
}
}
}
You have Error like: got error developer error exception of type 'google.googlesignin+signin exception' was thrown?
APK and AAB file have different SHA1 and SHA256. In Firebase, it's best to add SHA for both applications.
You can check the SHA from the AAB file in Google Play Console -> Your application -> Configuration -> Application integrity -> Application signing.
I added these SHA keys to Firebase and the problem was gone.
maybe my code will mess here beacuse I'm new into firebase stuff and there is lack doc for newbie like me, so I want to make save and load data from firebase, there is 2 scene the first for main menu and second one the main game,so when firstime login or auto login, user will load current user data from realtime database (I'm using firebase) also applies to user when back to main menu.
in the second scene itself, user load current user highscore data at first start then when game over if the score > lasthighscore that will save/update latest highscore to realtime database.
here the preview this is when I auto-login then playgame until game over:
it's supposed to be updated but not when back to main menu, I already try with player prefs since i erase all data when sign out so the highscore always be 0 and if login with other account that highscore is not belong to other account.
here my firebase script on main menu:
private void Start()
{
Time.timeScale = 1;
mainPanel.SetActive(true);
InitializeFirebase();
}
void InitializeFirebase()
{
auth = FirebaseAuth.DefaultInstance;
DBreference = FirebaseDatabase.DefaultInstance.RootReference;
auth.StateChanged += AuthStateChanged;
AuthStateChanged(this, null);
}
void AuthStateChanged(object sender, System.EventArgs eventArgs)
{
//This checks if the user (your local user) is the same as the one from the auth
if (auth.CurrentUser != User)
{
//this seems the same, but user could have been null before
bool signedIn = User != auth.CurrentUser && auth.CurrentUser != null;
if (!signedIn && User != null)
{
Debug.Log("Signed out " + User.UserId);
loginPanel.SetActive(true);
}
//this is important step, this user is the one you should be working with
User = auth.CurrentUser;
if (signedIn)
{
Debug.Log("Signed in " + User.UserId);
userNameShowText.text = User.DisplayName;
StartCoroutine(LoadUserData());
loginPanel.SetActive(false);
// //highScoreMainMenu.text = PlayerPrefs.GetInt("highscore").ToString("0000000");
}
else
{
loginPanel.SetActive(true);

}
}

yield return new WaitUntil(predicate: () => LoginTask.IsCompleted);
if (LoginTask.Exception != null)
{
//If there are errors handle them
Debug.LogWarning(message: $"Failed to register task with {LoginTask.Exception}");
FirebaseException firebaseEx = LoginTask.Exception.GetBaseException() as FirebaseException;

You don't capture child in this method. You can only capture all the data from the root. So, simply remove the child. It will work.
my solution to firebase realtime database not working was that my google-services.json wasnt updated after adding the google-services.json from firebase auth. firebase, project overview cogwheel, project settings, json on that page somewhere.
and my problem with firebase auth before that was that i didnt set the Client ID in unity, window, google play games, setup, android setup.. get the id from google play console, play games services, setup & management, configuration, and figure out how to add game server credentials
I am currently trying to create user authentication in unity and I am having some issues.
The code below is what I have at the moment and I keep receiving the error saying Auth does not exist in the current context.
Does anyone have any idea why this is? Probably a simple fix that I am just overlooking.

I do not see you ever creating the variable auth?
While you refer to it here:
auth.CreateUserWithEmailAndPasswordAsync(email, password).ContinueWith(task =>
So I assume you will have to create a variable auth and instantiate it with something related to FireBase.Auth (unless I am overlooking something).
