I GPG encrypt them and email them to myself using Thunderbird/Enigmail. I don't claim this makes any sense, I started doing it before password managers were popular. I keep meaning to start using `pass`.
I started using it earlier today actually (moving from KeePassX and have been meaning to for a while) and so far I really like it. As an Emacs user the Emacs integration plugin is also pretty amazing and it has import functionality for most known password managers.
