Add passwords to config.yml to manage multiple sites

If you are using SSH to connect to your sites then you can set up SSH aliases in your SSH config file. There are many advantages to doing this, one of them being that you use your SSH key to login to sites rather than having to type passwords. I do this with WP-CLI and it has been a huge convenience for me.
