google-authentication

I try make authentication using ClientLogin URL url = new URL("https://www.google.com/accounts/ClientLogin"); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setDoOutput(true); connection.setRequestMethod("POST"); connection.setRequestProperty("Email", "testonly%2Ein%2E2011%40gmail%2Ecom"); connection.setRequestProperty("Passwd", "mypass"); connection.setRequestProperty("accountType", "HOSTED"); connection.setRequestProperty("service", "apps"); connection.connect(); But I get Error=BadAuthentication . How I should correct my code? You should set the proper

I have gone through the google documentations for Oauth and AuthSub methods for authenticating and I've tried to google this without results. For Facebook, you can request an access token which is of length lifetime , meaning you won't have to be requesting a new token every few weeks. What about Google, and YouTube in specific, is there any authentication method which allows you to use that token permanently? In their documentation they state that they have long-life but no sort of additional detail, of exactly how long and whether or not you could actually get one which never expires.

In my Android application, I am trying to get google token to verify at my google app engine backend server. But I always get this exception : com.google.android.gms.auth.GoogleAuthException: getToken(Unknown Source) exception My code : private Account mAccount = AccountManager.get(this).getAccountsByType(GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE)[0]; private static final String SCOPE = "audience:server:client_id:" +Constants.WED_CLIENT_ID; String token = GoogleAuthUtil.getToken(LoginActivity.this, mAccount.name, SCOPE); I have tried every solution proposed in Stackoverflow. After several hours, I

I am attempting to build a web app that will be integrated with and installed into Google Drive. The user will be able to create and share my app's files in their drive. I am trying to write it using Firebase so I can leverage many of the great new features there. However, I'm having trouble getting the auth to work consistently across these two platforms. This is a client-side only app (at least for now) so I can't use offline auth and refresh tokens. Before Firebase auth, I would use the Google Identity Toolkit with gapi . This generally works fine, although it uses a popup flow which isn't

I am trying to implement Google SSO in my C# web application. It seemed to be pretty straightforward. Based on this tutorial , Google does its magic in the web browser to get an Id_Token JWT. I pass the token is passed it to my web service for validation and use it to match it to a user in the application. Although I am not sure if my approach with the server-side Google API is correct yet, my big hangup is trying to figure out how to work with the async call in the Google API to see what I get back. My code is pretty simple using the Google.Apis.Auth namespace: public async Task

I have integrated Google authenticate login in my app but after once login if I log out my account still every time app automatically sign in the old user account. MainAcivity public class MainActivity extends AppCompatActivity implements View.OnClickListener { GoogleSignInClient mGoogleSignInClient; private FirebaseAuth mAuth; private int RC_SIGN_IN=1; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mAuth = FirebaseAuth.getInstance(); GoogleSignInOptions gso = new GoogleSignInOptions.Builder

Does the ADC (Application Default Credentials) workflow only support Google Cloud APIs (for example, supports for Google Cloud Storage API, but not the Google Sheet API)? I'm referring to google.auth's default method - not having to store any private keys with the code is a great win and the main benefit of making effective use of the ADC (Application Default Credentials) setup. The following code works if I set the GOOGLE_APPLICATION_CREDENTIALS environmental variable to the private key file, say key.json. This is inline with the default method as per step 1 of the google.auth package: 1. If
