Lastpass looks nice and shiny. I tried it for a couple of weeks but I found one too many sites with which it did not play nice (refusing to populate the fields on my bank's login screen, specifically) so no, that won't do.
I was about to use my old approach of using GPG to encrypt a big ugly text file when I came across pass. Now that looks interesting. It uses GPG, it has useful off-the-shelf functionality (add/edit/delete/copy to clipboard), and it has a flexible structure that allows one to manage additional PINs and security questions. Importantly, I do not decrypt every one of my passwords simultaneously when I just need one of them, which is a less than desirable side effect of my current approach.
I shall install it and report back.
