On older versions of Windows, i.e. Windows Vista, 7, and 8/8.1, getting SSH running wasn’t easy. You had to do quite a bit to set it up. This was true for.

I install OpenSSH in Cygwin under Windows 7 to install Hadoop. I had OpenSSH installed previously, but with a password. All attempts to remove password are failed, so I re-installed Cygwin.

I want OpenSSH without password too and followed these. However, it does not let me leave a password blank. Why is that and what should I do? Additional info: I am running Cygwin bash with admin privileges. My Windows does not have a password set.
