What is the difference between PAP and MSCHAPv2 authentication?

Looking at picking a RADIUS protocol for authentication with Microsoft NPS and trying to understand to pros / cons for PAP and MSCHAPv2.

Best Answer

PAP uses a two-way handshake for authentication, CHAP uses a three-way handshake for authentication, and MS-CHAPv2 adds mutual authentication.

How you actually configure these depends on your router model, which you have not detailed in your question.
