Emacs Tramp asking for password

For about a week, every time I initialized emacs, Tramp would constantly ask for my password, both for sudo and for ssh.

This means that in the recent file list there is a sudo file or a ssh file, and everytime emacs initialize, it is trying to load this list (which requires it to re-ask for the password if it is not saved).

If this happens to you, the easiest fix is to clean the recent file lists by running:

    (setq session-file-alist ())
    (setq file-name-history ())
