I use Git; pass has integration with it out of the box (makes a commit for each change to the password store). I just push and pull periodically myself, but this could be automated. There is an Android app called Password Store that is compatible with pass and has Git integration built in.

I remember seeing some guy who had his `pass` Git repository public on GitHub and challenged the world to crack any of them. Myself, it's just git+ssh to a repository on my own server.

I use Dropbox but I also use git-remote-gcrypt[0] to encrypt the entire Git repo so that even the file names and sub-directories don't leak outside any of my computers or devices.

As others have mentioned, git / dropbox works well for this.

But personally I use a different approach. I rolled my own little rsync script that syncs files that I care about (passwords and other things) between my workstation and Chromebook (I run Linux natively on it).

Things like dropbox should be perfect for this, since the files are encrypted you don't need to trust anybody
