OAuth login through Google official webpage

OAuth 2.0 is Google's recommend login method for any product based on Google APIs. OAuth gives you access to your online data while protecting your account credentials.

Instead of inputting your data in third party tools, you present your email account and password on Google's sign in web page, and Google returns the client app an access token, which is used for subsequent requests. So, the third party client, like GDocsDrive, never handles your email or password.

• OAuth 2.0 is Google recommended login in method for third party clients.
• OAuth 2.0 is an open standard for authorization which is more secure.
• OAuth Authentication is already widely used on the web by Facebook, Twitter, Google , Microsoft and more.
