I use a system of increasingly difficult and unique passwords. Level 1: Social networks, forums, etc. simple 8 character alphanumeric. Level 2: iTunes, ebay, amazon. Longer alphanumeric with variations unique to each site. Level 3: Paypal, email, banking. Longer alphanumeric + special characters and completely unique for each site. Others: Some sites, like my ISP and bank send the password only by snail mail (I had to change my password once for DSL. It was not pretty). This goes into a lockbox. I'm looking into applications like 1Password.
