About Diceware
Weak passwords are a big flaw in computer security due to a lack of "entropy"
or randomness. For example, how many times have you used the name of a pet or relative or street
in a password, or perhaps the number "1". Not very random, is it? :-)
Worse still, if
passwords are reused between services,
that increases your security risk.
Fact is, humans are terrible at remembering random combiations of letters and
numbers, but we are great at remembering phrases of words. That's where diceware comes in.
Diceware is based on the proposal at
http://world.std.com/~reinhold/diceware.html
wherein virtual dice are roled 5 times, and the 5 digit number used against a lookup table of words.
4 dice rolls gives you 4 random words which are easy for a human being to remember, yet have
a high amount of entropy which makes them hard to crack.

FAQ: Why not use LastPass or a similar product?
By all means, feel free to do so. LastPass is an excellent product and I highly recommend it.
If, on the other hand, you prefer to be able to actually remember your
passwords, I recommend Diceware or a similar system.
