title: Passwords in Emacs tramp mode editing
body: <p>I'm using emacs <a href="http://www.emacswiki.org/emacs/TrampMode" rel="noreferrer">tramp mode</a> to remotely edit files over ssh. The problem is that every time I save the file I'm editing I have to enter my user password. I find that very annoying. How can I write my password only once / editing session?</p>
