title: Why firebase user still signed in after I deleted it from firebase dashboard
body: <p>I used Firebase Quickstarts for Android Auth sample, Then I created a user in firebase dashboard to login the user with email and password, the user logged in successfully.
  But when I deleted the user, it still logged in and showing the old user's email from (user.getEmail()) </p>
  
  <pre><code>// [START auth_state_listener]
      mAuthListener = new FirebaseAuth.AuthStateListener() {
          @Override
          public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
              FirebaseUser user = firebaseAuth.getCurrentUser();
              if (user != null) {
                  // User is signed in
                  Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getEmail());
              } else {
                  // User is signed out
                  Log.d(TAG, "onAuthStateChanged:signed_out");
              }
              // [START_EXCLUDE]
              updateUI(user);
              // [END_EXCLUDE]
          }
      };
      // [END auth_state_listener]
  </code></pre>
  
  <p>No users in my firebase dashboard and the AuthStateListener indecate that the user is signed in.</p>
  
  <p>how could that be possible ?</p>
