When changing a users password in the online tab against a contact, it is not obvious if the change has taken affect or not once you click set password. There is no confirmation and the 'set password' button remains greyed out. If you refresh the page it asks you to save the password (not sure if this is a chrome store password or something that needs to be done to complete the password change).
