Hi! I think I still did not get the key differences between the authentication protocols MS-CHAP-v2 and EAP-MS-CHAP-v2. As far as I know, both use (of course) MS-CHAPv2 for authentication purposes and both techniques do not need certificates. So where are the differences? Many thanks in advance! Enn

Hi, Regarding the detail information about the authentication protocols, please refer to the following articles: MS-CHAP-v2 Note: The third-party product discussed here is manufactured by a company that is independent of Microsoft.
