1.  SSH into your instance.

2.  Edit /etc/ssh/sshd_config and set PasswordAuthentication to yes.

One way to do this is to enter the command vi /etc/ssh/sshd_config, then scroll down toPasswordAuthentication.  Press i to go into text insert mode and change the no to yes.  Then press ESC, and type :wq and press enter to save and quit.

3.  Enter the command /etc/init.d/sshd reload. (for Ubuntu, enter the command reload ssh)

4.  Set your password if you haven’t already, with the passwd command.

Note: This was tested with SUSE Linux.  Directory and file names may be slightly different depending on your flavor of Linux.
