PasswordAuthentication resets to 'No' after creating a droplet from a snapshot that has this value as 'yes'

I’ve a snapshot that I have created from a droplet that has ssh key but I also want to be able to access it with a password so I set PasswordAuthentication to yes (inside /etc/ssh/sshd_config) and restarted ssh service (service sshd restart) before saving the snapshot. Now when I create other droplets using this snapshot and specify ssh key and then try to login with password I can not and when I logged in with ssh key to see whats wrong I noticed PasswordAuthentication was set back to ‘no’!! how can I force it to stay on the value I specified which was ‘yes’ ?

create a bash script like below in /root/ directory for example:

sudo sed -i "/^[^#]*PasswordAuthentication[[:space:]]no/c\PasswordAuthentication yes" /etc/ssh/sshd_config
sudo service sshd restart

Then create a systemd system(if using a systemd system like centos) to run this script on start up.

Did you ever figure out a solution to this? Kinda frustrating to spawn machines for a class and then have to go in and enable password logins again.
