Assuming SSH access:

# Turn on password authentication
sudo sed -i 's/^PasswordAuthentication.*/PasswordAuthentication yes/' /etc/ssh/sshd_config
# Reload SSHd configuration
sudo service sshd reload
# Set a password for the ec2-user
sudo passwd ec2-user

It is almost correct. but when i try to set passwd for ec2-user. passwd: Authentication token manipulation error. It seems that we don't have the default password that amazon gave up... – Kit Ho Jul 30 '11 at 16:24
