I followed the details of https://howtolearn.me/host-multiple-wordpress-website-free-aws-ubuntu-zpanel/ and I have created a wordpress site – however trying to update it I am required to provide some additional details. Hostname, FTP Username FTP Password. What I want to know is whether this information is from the zPanels FTP account option, or from the EC2 instance.

As a bonus question on the same subject, when connecting to my ec2 instance through SFTP where do I find the installed wordpress files?
