Integrated Windows Authentication uses the security features of Windows clients and servers. Unlike [[Basic access authentication|Basic Authentication]] or [[Digest access authentication|Digest Authentication]], initially, it does not prompt users for a user name and password. The current Windows user information on the client computer is supplied by the web browser through a cryptographic exchange involving hashing with the Web server. If the authentication exchange initially fails to identify the user, the web browser will prompt the user for a Windows user account user name and password.
