Is it possible to get on a server on Amazon EC2, if you shut yourself ssh access?

Hello. Made a huge mistake, my VPS had 2 users, one is root, another user added your user to root (/etc/sudoers.tmp)
user ALL=(ALL:ALL) ALL
and closed for root access via ssh (/etc/ssh/sshd_config)
PermitRootLogin no
I do not remember where and what I was doing, but the password is not necessarily requests a key from the server, the error "No supported authentication methods availible (server sent: publickey)".
Actually the question, on the server there is no chance now to get into, for example, through your personal account on Amazon EC2, we can only remove a machine?

Clearly, if the user ubuntu through which I came as soon as Incans created, then killed him :-) the prospects clear to me - Lola65 commented on March 19th 20 at 09:01
