Recover my locked keyring password (usr/bin/nm-connections-editor) message [Redhat-gnome]
I had the same issue, never changed the keyring password, now suddenly I couldn't login. What I did was, using Red Hat Enterprise Linux Workstation release 6.6 (Santiago):
my keyring was located in /home/[username]/.gnome2/keyrings
create a backup keyring file: cp -r login.keyring login.keyring_backup
Go to: Systems > Preferences > Network Connections
Connect to a Wifi connection listed, enter WiFi password, it will ask you if you want to secure your connection. Choose "Use Unsafe", now it will store a blank password.
You will now have a new keyring file in /home/[username]/.gnome2/keyrings
