There're many password manager that you can use to store passwords, such as KeePass. But me myself, I prefer to use Lastpass since it's integrated with multi Browser such as Firefox, Internet Explorer, Google Chrome. Aside from the browser integration feature, Lastpass store its password online, that way you can access your password database anytime anywhere via their webpage (as long as you're connected to the internet). There're many other features that is useful. Auto fill, Auto login, etc.
Now all I need is to remember is my Lastpass password. Let Lastpass handle your other sites password.
