The hash-filled Passapus. A simple application to generate a unique password which combines the site name and your master password into a long, hashed password, unique for each website. Source code available so you can see exactly how the password is created, and recreate it yourself, if you need to (or you can use passapus.com). You won't be blindly locked in to one app's view of "security" - it's flexible, but simple, but complex enough to create better online password.
