The 6 Steps to Google Authentication as Web Service in ASP.NET

Gone are the days when users were required to sign-in on different websites using different IDs. Initially, the number websites were less and it was not that tedious to create a username and password for authentication. As the number of websites and even users have increased, it is practically impossible for people to remember username and password for every website and it is difficult for companies to retain customers with this trend in place.

The current approach is to make use of the authentication via popular mediums. For example, if you are accessing a website on your Android phone, a website can authenticate you with the Google credentials and you would not be required to sign in on the website. As a user, you are not required to do anything extra, but as a developer, you would need to create a website that can fulfill this request. In this blog, we will learn how to get Google API access using Google+.

You need to be a Google API user which means that there should be an established project before you follow the steps below. If you are not a user, then follow these steps before proceeding to creating a client ID. If you already have a project, then, skip the next section and follow the steps in latter section.

Step 2: Click the dropdown icon on Project and select Create project. You will find this on the top left side of the page near the Google APIs.
