Obviously, you want your admin areas and other important stuff to be secure. So, you need a strong password. Preferably something long, and at the very least containing numbers as well as letters. The only problem with this is that you'll never be able to remember it... and keeping it on your pc can be rather insecure, as well as extremely annoying if your hd dies or you lose the file it's in.
So, just take something that is easy to remember (for you), and hash it using md5, sha-1 or something similar. You'll get a password that will be hella-hard to break for crackers, but you'll easily be able to get it any time you want. Just remember to keep your encryption app/page somewhere handy
