No this is not standard. What are you running on and which version of ssh?Perhaps you\'re using public key (without even knowing it? ;-))Si
The standard Sharp ROM doesn\'t come with ssh afaik, not can a root telnet login be made without editing /etc/securetty. Are you getting a terminal screen or a file transfer screen. If it\'s the latter then it may be that sftp is switching to ftp (which doesn\'t require a password).
I have never had to edit /etc/securetty to get root telnet access though with the Sharp ROMs
