Explanation:
Azure AD can support password-based single sign on for any cloud-based app that has an HTML-based sign-in page. By using a custom browser plugin, AAD automates the user's sign in process via securely retrieving application credentials such as the username and the password from the directory, and enters these credentials into the application's sign in page on behalf of the user.
Microsoft Azure Active Directory Access Control (also known as Access Control Service or ACS) supports federation with Yahoo! as an identity provider using the OpenID 2.0 authentication protocol.
