I have been looking around to find a way to change my unlock keyring password and everywhere I'been seeing it is accessible through "Application -> Accesoories -> Password and Encryption Keys" But I'm not sure which menu is "Application" or where is "Accessories" , I just searched for "password" and found a "Password and Keys" (that seahorse) I launched it and it's the window I faced : I'm not sure it's what I wanted . I'm using Ubuntu 13.10 ; Where can I find that "Password and Encryption keys" and change my & (Hardware)
