Hi Yourboydajoe,`
It seems like you may want to actually setup different user accounts on your server and then create passwords for those individual user accounts. Just a note, typically a webserver with SSL runs on port 443 and an OpenSSH server runs on port 22.

Here is a Digital Ocean tutorial on how to create new users, and how to give them super user privileges.

(I am assuming that you are running ubuntu or Debian but if not just search for how to add users in (your os).

https://www.digitalocean.com/community/tutorials/how-to-add-and-delete-users-on-an-ubuntu-14-04-vps

Once you complete that tutorial you can change accounts from root (which I am assuming you are logged into) to whatever account you just created by typing:

su - joe (or whatever you named your account)
and then passwd

If you want to change your default ssh port this is a pretty simple tutorial

Hope this helps!
Welcome to the World of Linux!
Happy Hosting :)
