Jacob took a look at standalone GTK-based password remembering tool GPass recently, and if you’re not on KDE that is a very useful tool.
KDE users however have a built in architecture called KWallet, which is designed to securely store passwords and other sensitive information but also includes integration with KDE (so for example you can have passwords auto-filled, pulled direct from your encrypted, secure KDE wallet).
In fact, you might already be using the KDE wallet. If you use Kopete for IM and have chosen to save your passwords, for example, you are. If we extend the Kopete example for a moment, the first time you choose to save a password in Kopete, you will be asked to set a password for your default KDE wallet.
It is this password that is your ‘master password’ and is used to encrypt all of the information stored inside the wallet.
