Passpack gives you the tools to organize your passwords all in one place, the way you want them, with tags. For example, your Amazon.com password can be tagged both "shopping" and "books". Your Mac's account can be tagged both "shopping" and "clothes". If you click on the "shopping" tag inside your Passpack account, you'll see both your Amazon and your Mac's entries. If you click "books" you'll see Amazon only.
A great idea for a weekend project is to change all of your passwords into something unique for each account. Now that you no longer have to remember all your passwords, use Passpack's password generator to create strong, unguessable passwords and significantly reduce your risk of identity theft.
