How can i edit my keychain on websites? I changed my password to a web site to log in and keychain is the old password.

Im running the latest Yosemite

Just launch Keychain application and enter the site name in the search bar at the top. Then double click on the Keychain entry for that site and enter your admin password to allow editing. Then update the password to the new one.
