Security: Passwords

There's not much to say about this one that's not common sense, but more common sense is better.

Passwords should be "strong" -- that is, not easily guessable or hacked via brute-force. The longer it is, the better. Combining different types of characters (upper-case letters, lower-case letters, numerals and 'special characters' like punctuation) is even better. Your birthday, the name of your dog, etc. are all very, very bad passwords. They're not as good as two-factor authentication, but often they're all you get to work with.

Sometimes you have to crank out password after password (or one Really Good password) and that's a job best left to a random password generator. If you just need some passwords, I like the PCTools Random Password Generator web page.
