To allow us to login to your Linux server, we use SSH Keys. That way, we do not need to have a password of your server. And you can instantly deny us access by removing our keys.
You can find our SSH keys here:

Add the contents of this file to ~user/.ssh/authorized_keys, where user is the username as who we may login.
