Kwallet - Password Manager for KDE
KWallet is an utility bundled in KDE (K Desktop Environment) that stores passwords from many KDE and KDE-enabled applications, such as KMail, Amarok, Kopete, KRDC, Chromium etc. Once enabled, a KDE user is asked for his/hers "master" password upon booting, and does not have to provide each password when he/she runs a KWallet-registered application.
