A generic username and password for all those sites that make you log in before you get to the good stuff.

If you don't feel like giving up your privacy just to read an article, try logging in as cypherpunk or cypherpunks, using the same word as the password. If the account doesn't exist yet, and you're not required to pay to use the site, then by all means set up a new account in the name of cypherpunk(s). Future users will thank you.

It should be noted that you don't need to use a login/password on the New York Times website if you go to http://partners.nytimes.com instead of http://www.nytimes.com.
