I have used for year a KISS (Keep it simple) solution: I have a directory encrypted with encfs where I keep all sensitive data. The directory is shared through dropox by all my devices. In this directory I keep a plain text file with all passwords, domain, used email.... It is actually a YAML file cause I also have a simple groovy scripts that pastes the password (given domain or key) in my clipboard, but any text file would do the job. As simple as that.
