I do not like password managers.
I managed to get the kwalletmanager window displayed, and disabled kwallet, I thought.

When I edit my WiFi connection, I keep getting a message that "The application 'KDE Daemon' has requested to open the KDE wallet".

Is it required?
Is it hard-coded?
How do I get rid of it?

Annoyed,
Jim

WPA2 or WEP passwords have to be stored somewhere to access a secured WiFi connection, and that place should be a secure place. Hence, KWallet.

I don't know why you "don't like password managers," because I could not think to live without them. Sensitive information must be stored in such a way that it cannot be trivially accessed by snooping around on your hard-drive ... which a Java or JavaScript application could be doing while you're visiting your favorite p0rn web-site or what-have-you. Any file which contains your user-name probably contains your password too.

You actually want to store all of this sort of information in a cryptographically secure place, i.e. a wallet system.

Good points.
However if a password manager handles my passwords so I only have to remember one, I become dependent on one machine.
I don't much like that, and I do not trust the security of the 'Cloud'.

Passwords to change WiFi connections have nothing to do with Password Managers, or wallets, or whatever.

I didn't used to use password vaults because they were annoying, but I have become a confirmed user of keepassx. It's cross-platform, so, when I add something to the database, I can copy the database file to whatever computer I am using.

It even works on my Android with Keepassdroid.
