Configure digest authentication in SharePoint 2013 web application

We can configure digest authentication in SharePoint web application zones. Zones are the logical paths for access to a web application. We can create five different zones for each web application in SharePoint. We can use IIS Manager Console to configure digest authentication one or more zones in SharePoint web application.

Digest authentication encrypts user credentials to increase the security. We can send user credentials in MD5 message digest. Digest authentication will use challenge/response protocol for authentication process. To authenticate the use client needs to send MD5 message digest in a response contains secret password string.
