If you are writing about a terminal connection... I mean as a connection to a Linux system... then you must first use the TELNET protocol and not SSH.
Namely, SSH requires a password (for encrypted connections). An empty password does not work in the case of SSH protocol. This only works for the TELNET protocol. So if you use TELNET, it works without a password. The username is "root" and the password is blank - i.e. the ENTER key.
The problem is that pre-installed SSH "service" has an unknown / blank password as a default, so the SSH connection doesn't work until you set your own password (for example, with the "passwd" command via Linux-Shell).
