I didn't add a user name and password for this app. How does it know my credentials?

Version 2

    Your administrator has probably configured the app to share credentials with other apps using something called a directory password. This usually happens when your network user name and password, also known as your AD account, is used for multiple other applications. For example, you might sign in to your desktop using that account and you might use it to get to an HR application, an expense reporting site, and Salesforce.
