After updating from Precise to Trusty I get a popup requesting to unlock the keyring for Network Manager after each login (autologin is enabled). On the net people advise to make the connection available for all users or install libpam-gnome-keyring. I did both and none helped to solve the problem. I know of the method to unlock the keyring by setting a blank password but this seems to be a bad solution in terms of security. I only want to connect to WiFi without password check, not to unlock the keyring for everybody. :)
