I upgraded from 6.1.9 to 6.9.2 recently.  Basically did a fresh install of 6.9.2.  I am trying to connect to the new server as root using Putty on Windows 10, but I get "Using keyboard-interactive authentication".  Since root has no password, I just hit enter at the password field.  I then am greeted with an "Access denied".

 

What am I doing wrong?  This should be simple with a fresh install with no plugins or apps.  Any help would be appreciated.

 

Here is the log:

I'm not sure I remember correctly, but I think I saw something in the 6.9 release notes that it's not allowed with no root password anymore. Which is a good thing.

It's documented here: https://wiki.unraid.net/Manual/Release_Notes/Unraid_OS_6.9.0#SSH_Improvements
