8 million leaked passwords connected to LinkedIn, dating website (ars technica)

I've downloaded Bruce Schneier's password manager, used a new safe password, added some passwords to the tool - and the next week when I tried to access it, I forgot the master password :-( The problem of rarely used password.

By the way, currently I need two passwords (disk encryption, login) on my windows laptop to get to a point where I can start the password manager. Life sucks.
