We need passwords for everything these days — I have about a million, covering all my own stuff: bank accounts, blogs, computer, email, you name it, and a whole bunch of client stuff: ftp passwords, logins … Yup, passwords are a major pain, and thinking them up is always so hard. So it was interesting to read Eric Meyer’s trick for Password Production.
The general idea is to pick a two-word combination you can easily remember. For example, suppose you’re a big fan of pizza and Pepsi, and would have no trouble remembering those words.

It looks fairly random, and yet is very easy to recreate because the seed words are so easy to remember. If you have trouble remembering the exact sequence of letters, you can just write the words down on a piece of scrap paper and follow along.
