What Happens When you Type Your Password into Windows?

I was interviewed by Jason Howard from the Windows Insider team and we talked about Windows Authentication and stuff.

Let's talk Azure AD join and what that means to a Windows device. What's it mean to be joined to something?

Kerberos is an authenticated key agreement protocol based on the Needham-Schroeder protocol. That's too complicated -- let's break it down a little.

Have you ever wondered how authentication works for things like Remote Desktop?

There's a little known feature in Windows called the KDC Proxy that lets clients communicate with KDC servers over an HTTPS channel instead of TCP.

Tl;dr; It’s really not. As we build new protocols we should remember all the things we got right with Kerberos and account for all the things we got wrong.

How I ported Kerberos.NET to .NET Core.

Kerberos.NET now supports claims presented by Active Directory.

The AES cryptographic algorithm was added to the Kerberos.NET library.

Seamless Single Sign-On lets you sign in to Azure AD using Kerberos. Here's how it works.
