Why am I being asked for the current UNIX password when logging in with SSH?

Hi,

I’m really very new to all of this. I’ve set up a new droplet for discourse and am trying to get access to it.

I followed best practices and set up and SSH using Putty on my Windows OS computer. That all seems to work fine.

The problem is after I’ve logged in the system asks me for the current UNIX password for root so that I can set up a new one. From what I understand if I’ve set up SSH I shouldn’t need a password. Is that right?

I did a root password reset on the droplet yesterday but the password that was emailed to me doesn’t work. The window just closes which I assume means incorrect password.

I’m not too sure what’s going on because all of the help guides I’ve read say this shouldn’t be happening.
