When choosing a password, we have all probably heard at one time or another that the more complex, the better. The real question is 'better for whom'? Consider the following two passwords: G00d4B!#j6 and "My favorite pet is my turtle." Which do you think is stronger? Which do you think is easier to remember and type?

Due to advances in computing power and increases in the effectiveness of password crackers, it is becoming evident that longer passwords are actually better. Therefore, it is recommended that passwords be 15 characters or longer. Naturally, we don't want to move into the realm of passwords so long and complex that we're reduced to writing them on sticky notes and plastering them all over our desks, either (of course, *you* don't have one stuck under your keyboard, right?). So to make it easier to remember a longer password, use a passphrase. A passphrase is simply a sentence or pseudo sentence, like our second sample password. If you're feeling really adventurous, you can even include punctuation, spaces and misspelled words.

Going back to our sample passwords, I know which one I would rather use. Most systems in use today support these longer passwords, so the next time you're changing yours, why not try out a passphrase?

One final note: keep in mind that certain systems may not accept leading numeric or special characters for passwords, such as the University's Banner system. In those cases, ensure that you use a password that begins with a letter
