I don't think there's a default account. My guess is, if the SSH key does not work, it will always ask for the password. You can setup a new account/password to avoid such issue in the future.
If your virtual hosts use the same php external app, and no suEXEC enabled, then it should share the same processes. But it's a good idea to separate it for security purposes for a shared server.
Have you tried the SSH method with the SSH key? Does it work?

Hi,
It was introduced with v1.7.19 and has been fixed with v1.7.19 build 2. If you installed it from the LiteSpeed repo, then you can run the package update to have the new version installed.
You can simply update system packages on the origin server, e.g. "apt update && apt upgrade -y". Otherwise, you can launch a new server, and migrate the data from the old server to the new one.
Let me know if you have any questions.
