Paste this script to your EC2 userdata during launch to enable password ssh for your first login. Change user and pass by changing lines under TODO in the below script.
#!/bin/bash
sed 's/PasswordAuthentication no/PasswordAuthentication yes/' -i /etc/ssh/sshd_config
systemctl restart sshd
service sshd restart
#TODO: replace bob with your desired username
useradd bob
# TODO: replace password123 with desired password and change bob to your username chosen in useradd
echo "password123" | passwd --stdin bob
If you make no changes to the script , you can login to EC2 after a few minutes using this command. Passoword is password123 . Replace the IP with your EC2 IP
