google-oauth2

I've implemented a Google OAuth2 login flow in my web-server app (using python/flask). My app redirects the user to Google, where they sign in with Google credentials and get directed back to my app. I'm having trouble deciding how to implement the Logout functionality for this app. I can clear the app's session cookies, but that doesn't log the user out of their Google a/c. So if the user hits Login after logging out, the redirect goes to Google and since the user is still signed into Google, they're automatically (without even being prompted to re-enter credentials) signed back in to my app.

I followed the instructions in this great post , to setup account linking between my app's server and google actions. In the auth process, I requested " https://www.googleapis.com/auth/calendar " scope permission. I managed to get the auth token on my server by calling app.getUser().accessToken But when I make a request to googleapi calendar, using this piece of code: const google = require('googleapis'); var calendar = google.calendar('v3'); var eventData = { auth: myAuthToken, calendarId: 'primary', resource: { 'summary': 'My Event', 'description': 'Event desc', 'start': { 'dateTime': '2017

I am making a java command line application packaged in a single JAR file that uses some of Google's API. I need to set up a GoogleCredential object from a private key "Credentials.p12". GoogleCredential credential = new GoogleCredential.Builder() .setTransport(httpTransport) .setJsonFactory(jsonFactory) .setServiceAccountId("xxxxx@developer.gserviceaccount.com") .setServiceAccountScopes(Arrays.asList(DirectoryScopes.ADMIN_DIRECTORY_GROUP, DirectoryScopes.ADMIN_DIRECTORY_USER, DirectoryScopes.ADMIN_DIRECTORY_ORGUNIT)) .setServiceAccountUser(emailAccount) //THE CODE BELOW IS IMPORTANT: I need

I want to implement Google Oauth2 on my project. My main goals are accessing the google-people API in order to display profile information, and google drive. Because I'm new with this, I activated several APIs and -most of the times- succeeded in getting info. Only the People API is causing me problems, and I don't get why. Here is what I'm doing (I'm skipping all the login part). Defining the scopes: $client->addScope("https://www.googleapis.com/auth/drive"); $client->addScope("https://www.googleapis.com/auth/youtube"); $client->addScope("https://www.googleapis.com/auth/contacts"); // this is

I am trying to use a service account to access Directory API ( https://developers.google.com/admin-sdk/directory/v1/reference/users/list ). The simplest task is to list users in the organization. That works well with my user account, tested with the OAuth 2.0 Playgorund. But I need to use service account. I am following documentation for two-legged OAuth ( https://developers.google.com/identity/protocols/OAuth2ServiceAccount ) and implementing REST client in Powershell API Access enabled in Google Admin Console The service acount is created and P12 credentials downloaded. The account is

Sometimes when a user logins into a site with Google's OAuth 2.0 they choose the wrong account to login with. Normally this isn't a problem if the user has more than one account registered with the browser, google will automatically show the user select screen: But if a user has only one account and is logged in, this screen is skipped. Instead I need Google's sign in panel to always appear, so that I can be sure the user has the option to try and enter the correct account. I tried using approval_prompt = "force" , but that forces the acceptance of permissions rather than simply showing the
