I have been using a little program to save and manage my passwords for a few years now. It's called PasswordSafe.
A few things I like about it:

- It generates passwords with upper and lower case letters, numbers and symbols.
- It is very easy to use
- You don't type passwords anymore. All you do is double click, the password is saved to the clipboard, and you can paste it to your login.
- You only have to remember one password: the one that open your database of password, and each of your account can now have a different and more secure password.
