Press the Dash icon, the top left icon. Type in the search string "key" or "pass" and see if you get a hit. If you do, you should see a keyring icon with the words "Passwords and Keys". If not, go to the Ubuntu Software Center and enter "seahorse" to initiate a search, as that is the program manager for the passwords. You should see the words "Passwords and Keys". That's the extent of my knowledge.
