+* Passwords
+  This was a little more work than I expected... =password-store=
+  provides a nice interface to =pass=:
+
+  #+begin_src emacs-lisp
+    (use-package password-store)
+  #+end_src
+
+  However, in order for it to actually work, EasyPG had to be
+  configured to use loopback for pinentry.
+
+  #+begin_src emacs-lisp
+    (setq epa-pinentry-mode 'loopback)
+  #+end_src
+
+  =gpg-agent= also had to be configured to allow loopback for
+  pinentry -- this was done by adding =allow-loopback-pinentry= to
+  [[file:~/.gnupg/gpg-agent.conf::allow-loopback-pinentry][gpg-agent.conf]].
+
+  With that all working, all that remains is to add a convenient
+  keybinding for getting a password, which is done by the function
+  =password-store-copy=. =C-c C-p= does conflict with /some/ modal
+  bindings, but I think that's fine as most of the time I'll need a
+  password it'll be in some X window anyway... and besides, =M-x
+  pass-co RET= isn't bad for when it does happen to conflict.
