I used to keep a list of individual passwords in a GPG-encrypted container. Then I would copy-pasta them around, as needed. I realized this is just a huge security hole, particularly since I use ClipX (multi-clipboard tool, shows a clipboard history on Ctrl+Shift+V). Also, GPG would mysteriously eat the file on one machine every now and then.

Now I mostly use pwdhash.com and three or so tiers of passwords. Works well. I still have the GPG file, but I use it mostly for keeping track of my gibberish answers to dumb security questions ("who was your senior prom date/where did you meet your wife").
