Passwords - How Strong Should They Be?

Passwords are used to secure everything from bank accounts to cell phones, and also computers. Developing strong passwords is a necessary way to protect information. But the exact way to do this has always been up to debate.
Should we create strong, complicated passwords that we can’t remember, but need to write down on paper? Or should we use passwords that are simple enough so that we can remember them, but which increases the risk that they can be cracked?
Most security experts advise against using numbers that can identify you such as birthdays, social security numbers, and even your telephone number should not be used. Instead, they advise the following steps:
- Use a combination of letters and numbers that are memorable to you.
- Do not write this information down in an office environment.
- Use different passwords for different accounts. You don’t want all your accounts attacked if your password is cracked.
- Have a bunch of passwords? Consider using password software.
- Using smart cards is also an option.
And change your passwords often to protect your accounts.

Any one use passphrases? ie. phrases at least 14 characters long, ignoring all complexity of mixed case, numbers, signs. For example, “My monkey wears pants.”
I switched to passphrases a little while ago. OS X’s built-in password evaluator seems to think they are better than my old complex passwords that are difficult to remember or tell anyone.
The Recovery Speed charts suggest a supercomputer would take about a billion years to crack this kind of password. That seems good enough to me.
Passphrases? Anyone? No?

I’m hip to passphrases. Just run it together and it becomes a password: Ihave6cats4you
