How to set ssh password on nodes?

Tried using pelican-1.8(amd64) on vmware frontend and nodes. After I ran 'pelican_setup', I was now required to give the 'user@10.11.12.2' ssh password? I dont know what to give since I didnt set any user password on the nodes,yet. Is there a step I have missed?
Please take note that i'm trying to use the nodes thru PXE boot-up and that the nodes are using 'bridged' networking thru vmware.
