I'm having some troubles that until now i could not fix. The first is a doubt, acording to Firebase the header will contain a kid that must match with some public key provided by them in this site: https://www.googleapis.com/robot/v1/metadata/x509/securetoken@system.gserviceaccount.com well I have done some tests and I figured out that this

问题 I want to be able to check if an email address is already been used (so if somebody put test1@test.com but another user already registered with that email account). I have a simple test if it has NOT been used an image view shows a green arrow, if it HAS been used then it is red x when I create the user I use the following code FIRAuth.auth()?.createUser(withEmail: email, password: password, completion: { (user, error) in if error == nil { self.ref.child("userEmails").child((user?.uid)!)

问题 I have just updated my Xcode to Xcode8 and I have converted the project to swift 3. In signIn function here: Firth.

I'm kinda going pretty mad about this. And the error is specifically: I/System.out: The specified authentication provider is not enabled for this Firebase. This is my MainActivity.java class: public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState)

问题 I am trying to do Firebasegoogle authentication, but everytime am getting public void onComplete(@NonNull Task<AuthResult> task) task.isSuccessful() as false with the follwing exception com.google.firebase.FirebaseException: An internal error has occurred.

问题 Here is my scenario, if user sign in with google provider first in my web application following after sometimes the same user may try to login in using facebook provider, now if the user's facebook provider email id matches with the previous google provider mail id in firebase, it will throw error like "account-exists-with-different-credential" in this case firebase will give us the facebook provider email id and instructed us to get the "Asks the user his password." what password will I ask
