Comment 5 for bug 276384

I think, placing the wireless passwords out of the keyring is not the ideal solution, because the keyring is being used for other passwords as well. (Like Samba shares or various instant messengers.) So just dealing with network-manager decreases security but doesn't solve the problem at all.

If you personally don't care about encrypted password storage, I think you could set your gnome keyring master passphrase to an empty one. Of course this will cause your whole keyring to be saved to disk unencrypted.

I personally don't mind typing the keyring password once during login and use thinkfinger for sudo, screensaver, etc.
