Once you have done this, the Times allows your password to be stored on your computer so that you don't have to bother typing it again. It is best, if your password is not saved, to visit the Times site and log in to the front page. Once you have successfully logged in, then come to this page to access these links. If you click one of these links, and are then asked to log in you will not be able to get directly to the requested page for some reason. Then you should be able to proceed.
