I want to read/write some content to Google Drive Programmatically from a ASP.NET MVC Application. Here i want to use Email ID and Password as hot coded instead of navigating user to authentication page.
I looked at some examples, all are redirecting user to Google authentication page. But My requirement is to use a fixed Google user account.
You can no longer use username/password for authentication. Just let go of it.
You can use the steps in the answer here How do I authorise an app (web or installed) without user intervention? (canonical ?) to achieve what you are looking for

I have searched long and far for this on Google Identity documentation but my question seems to be out of it's scope (https://developers.google.com/identity/protocols/OAuth2).
This is what I have:
I have an app that is using Google's PHP Client library to authenticate a user via oAuth2. My application stores the retrieved token & refresh token from a user. I am able to use this token and refresh token to pull in information from various Google API's (Drive, Calendar, Mail, etc). I am also storing a cookie in browser to keep the user logged in to the application when the user closes the browser. I have created a simple way for users to login to the application via a QR code that matches up their stored token and refresh token. After the first login they are able to simply use a badge to login to the application.
This is what I want but don't know how to do
When a user logs into the application with their QR badge everything work perfectly (I am still able to pull in anything via the PHP Client Library/Google API's), however when a user goes to Gmail, Drive, or other Google service, Google is asking them to login (it's because they are not technically authenticated with accounts.google.com (only my application)). Is there a way to programmatically authenticate a user to accounts.google.com via a stored token/refresh token?
I was searching for a proper way to implement authentication of users with Google accounts into an app I'm developing. One thing led to another and I found this:
https://github.com/thephpleague/oauth2-google
They have a few implementations depending on how you may wish to implement OAuth2 (via separate repositories). I believe this directly answers your question, albeit 3.4 years later. Hopefully it will help someone else who is looking for this info.
Couple of questions:
I implemented the authentication process with OneDrive. My desktop application is designed for end-users. Every time the application is launched the little browser window pops up asking the user to confirm access...and if more than 1 hour passed user needs to provide username and password. Is there any way that end-user with SOME SORT of saved credentials (or user Code +user Secret, or API code + API secret) will be able to invoke the application and not be prompted by browser form (that currently requires login - if access token expired - or confirmation)?
The goal of my application is file sharing - that is, one end user may send URL (to the file that he uploaded to OneDrive) to another user and the latter should be able to download the file by clicking on the link (without any prompts, exactly like in manual process of sharing link to the file in OneDrive). Is it possible? If yes, how to achieve that? That is, how do I get that URL? Redandent to say that I am looking for a programmatic way to obtain a URL that will achieve the above described)
The OneDrive authentication process uses Microsoft account, which supports OAuth 2.0. You should be able to point the user to:
https://login.live.com/oauth20_authorize.srf?client_id=CLIENT_ID&scope=SCOPE&response_type=code&redirect_uri=REDIRECT_URI
Once the user authenticated and authorizes your app, the user will be taken to REDIRECT_URI/?code=CODE, where your app can exchange that code for an access token at:
https://login.live.com/oauth20_token.srf?client_id=CLIENT_ID&client_secret=CLIENT_SECRET&code=CODE&grant_type=authorization_code&redirect_uri=REDIRECT_URI.

Is it possible to achieve Azure Active Directory authentication without going to browser window? I will have username and password via the mobile app login interface.
I need to achieve below scenario:
Use open mobile application (ios/android)
Enter Azure AD username and password to app login screen - e.g. user#tenant.onmicrosoft.com & password
I pass those information to .net web service - which need to call some Azure AD api to validate user credential before proceed to perform other business logic/make database calls
Any recommendation? I DON'T want user to redirect to any login window/page as this will not be good user experience.
I have already checked few different articles but not satisfactory response yet.
Thank you for your time.
I believe below link is helpful.

While implementing the Facebook Connect to a web application , its possible to show Facebook Sign up page in a pop up and once logging in and Granting permissions are complete, its possible to Authenticate Again in PHP and to get the necessary details of the user, - id, email etc.
I believe, thats secure because, the User Insertion is not based on the Ajax Request Parameters.
Is it possible to do the same with Google Plus Login also ?
Means - Logging in to Google - Using Javascript SDK, asking permissions, Authenticating all done in a Pop Up Window. and then, Creating a new user with the Help of google-api-php-client ??
Yes, what you're trying to do is outlined with https://developers.google.com/+/web/signin/server-side-flow which includes some PHP code samples to help you do this. In general, the steps at authentication time are:
User clicks the "Sign in with Google" button which may pop-up a new window at Google prompting them to log in and authorize your webapp.
After they do so, a one-time code is sent to a JavaScript callback you specify.
Your Javascript method sends this code to your PHP server.
Your PHP server uses the client library to contact Google's server and exchange this one-time code for an access token and refresh token, which you keep and use to perform actions on the user's behalf.
I'm trying to add Azure Mobile Service authentications to my WinRT app. I got everything working and I can sign in with all the 4 social media accounts(Facebook, Twitter, Google and Microsoft Account). But when I close the app and restart it, I have to write my user name and password even if I check the Remember Me button on either one of the options. Let say I logged in with my Facebook account, what I want to achive is, when I restart the app and click Login with Facebook, it shouldn't ask my username and password but automatically authenticate me. The remember me button seems to not working. Is there a way to achive this?
Thank you for the answers.
Edit: I'm using C#/XAML for my my app.
The following blog post covers caching the user's identity. http://www.thejoyofcode.com/Setting_the_auth_token_in_the_Mobile_Services_client_and_caching_the_user_rsquo_s_identity_Day_10_.aspx

Note
... This method is easy to configure and supports multiple providers. However, this method also requires users to log-in every time your app starts. To instead use Live Connect to provide a single sign-on experience in your Windows Store app, see the topic Single sign-on for Windows Store apps by using Live Connect.
