Firebase reset password using provider accounts

问题

I am using firebase for a little while and I find a little issue I think it's not a big issue, that issue is that when I login with provider account like: "facebook" account and I enter facebook account email in forgot password field this should show an error but what happens is that the method success, my question is that when I reset password is my facebook account password changed or what happens, heres my method below:

 mAuth.sendPasswordResetEmail(Email).addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    if (task.isSuccessful()){Toast.makeText(forgot.this,"Send",Toast.LENGTH_SHORT).show();mProgress.hide();}
                    else {Toast.makeText(forgot.this,"Not send",Toast.LENGTH_SHORT).show();mProgress.hide();}}});}

I need a method that check if user email is an provider email like "facebook,twitter and google" and return.

So any help brothers.

If you need an API to check what type of provider is associated with an email, you can use fetchProvidersForEmail. https://firebase.google.com/docs/reference/android/com/google/firebase/auth/FirebaseAuth.html#fetchProvidersForEmail(java.lang.String)

As for resetting the password of an account that had a Facebook provider linked to it, it will unlink that Facebook account and transform it into a password account. The user will need to re-link the Facebook provider. This behavior allows the user to recover an account in case it was hijacked and modified by another unverified user.
