Question about DUO Free


Can I use DUO FRee version on Windows 2012 R2 server?

Thank you


Yep, you’re just limited to features in the Admin Panel, seen here: Pricing | Duo Security


So with Duo Free, does it allow to protect RDP?


Yes it does. Here are the docs for that integration: Duo Authentication for Windows Logon and RDP | Duo Security
