What are Pod Users
Pod users are SSH/SFTP users that JungleWP creates on your server. Every website belongs to and runs as one of these Pod users. You can log in to your server as a Pod user to deploy or update a website's code or view a website's log files.
By default, JungleWP creates a separate Pod user for each app. This provides security isolation between your WordPress websites. Additionally, running each website under a separate Pod user makes debugging easier and provides a way for you to give your developers or clients access only to the websites they should have access to.
