KeepassX is a very useful cross platform password manager program for handling all your web passwords. It utilizes a database file which can be opened on any platform if you have KeepassX installed. You can keep your password database at web locations like DropBox so that you can access it from any device and as it is encrypted, even if someone hacks your Dropbox account they still can't get at your passwords.

Get KeepassX for Centos 6/RHEL below.
Install it with
$sudo rpm -Uvh <file_name>.rpm
A very useful tool for Linux (and other OS's) which has proved to be indispensable in the ongoing battle with cyber terrorists.
