Writing Secure Authentication Code with OAuth2 and the Office 365 APIs

In order to use the Office 365 APIs, you must first register your application with Azure Active Directory and then you must write the code to authenticate and to acquire access tokens using one of the OAuth2 authentication protocols supported by Azure Active Directory. This session examines three different styles of authentication with OAuth2 including Implicit Grant, Authorization Code Grant and Client Credentials Grant and takes the time to explain how to pick the most appropriate authentication style given the type of application you are building. The session also teaches you how to program using the Active Directory Authentication Library for .NET (ADAL.NET) and the Active Directory Authentication Library for JavaScript (ADAL-JS) to write robust, maintainable authentication code that follows Microsoft recommendations and best practices.
