I was always a bit wary of these services. They sound great, and the convenience is amazing, but I have not much of an idea how everything works behind the curtain.

I went with unix pass installed inside of a FreeBSD jail. It's more complex than auto-filling with a browser plugin (though those exist), but as long as I can get an SSH terminal I can get to my passwords, and various other bits of data. You have to allow password login from sshd (which isn't ideal, but I was going for "access from anywhere I can get an SSH session), so your passphrase had better be good. And you need to have terminal discipline to be sure you clear the screen if shoulder-surfing is an issue.

But it has the advantage of knowing exactly what's going on at all times. And, for added benefit, there are only a handful of things you need to have printed out and stored in a safe or whatever so that your family can access all of the encrypted important stuff if you get struck by lightning.
