Secure password wallet manager for KDE 4
Testbed Distribution: Ubuntu 10.04 LTS (lucid) / slackware64-13.1
Installation: Via APT / Installed by default
Version: 4:4.4.2-0ubuntu1
Description: The KDE Wallet system provides a secure way to store passwords and other secret information, allowing the user to remember only a single KDE Wallet password instead of numerous different passwords and credentials.
KWallet Manager is a utility for viewing and editing information stored in the KDE Wallet. This package is part of the KDE 4 utilities module.

Unfortunately, I could not run it on Gnome which is the default desktop environment in Ubuntu! Consequently, I installed kdebase and logged into KDE desktop environment to be able to test it. Moreover, I have tested it on Slackware64 13.1. However, it is well integrated with KDE apps.
Firstly, one of its nice feature is being able to use a different wallet for local passwords, also it has a simple search. Additionally, I have found a Firefox add-on for KDE Wallet password integration http://www.guillermomolina.com.ar/index.php/en/proyectos/firefox-kwallet-extensionhttp://www.guillermomolina.com.ar/index.php/en/archivos/cat_view/53-firefox-kwallet-extensionhttps://addons.mozilla.org/en-US/firefox/addon/49357/ which, as a result of integration with KDE, can exchange credentials with Konquerorand other KDE applications. However, first saved passwords can be shared with konqueror and others are saved into "Firefox" kwallet folder, because konqueror does not support storage of more than one password per url.
A disadavantage of KDE Wallet is that credentials are limitted to Binary Data, Maps, Passwords and Unknown and each type has only one or two fields; also, only one level of folders is supported and there is no nested folders to create a tree like stucture (likde GPass and Seahorse).
