KWallet is annoying
People often complain about KWallet prompting them for the password (too often). So here’s the simplest solution to this: Simply use an empty password for KWallet, and KWallet will never prompt you for the password again.
Change KWallet Password
If you have already set up KWallet with a non-empty password, here’s how to change it:
1) Run ‘kwalletmanager’ and click on the KWallet icon in the systray – the icon might be hidden so you’ll need to click the little arrow in the systray to show hidden systray icons.
2) Right click on your wallet in the kwalletmanager window and select Change Password
3) Enter an empty password, simply by clicking OK without entering anything.
