We are continuing with part 2 of "Behind the Login Screen - Understanding OS Authentication." If you missed our first episode, I highly recommend giving it a listen before diving into today's content. In part one, we started to explore the fascinating world of operating system authentications, focusing on Windows, Linux/Unix, and Mac OS. We discussed how hashes are used in authentication, the concept of salt in passwords, rainbow table attacks. 

In today's episode, we'll build on that foundation and delve even deeper into the topic of OS authentication mechanisms. So again, if you haven't already, make sure to catch up on part one to get the full picture.

Now, let's get started with part two of our journey into the world of OS authentication! lets look at one of the trending security news this week, and that is:
