FBI.gov: Recent guidance from the National Institute of Standards and Technology (NIST) advises that password length is much more important than password complexity. Instead of using short complex passwords, use passphrases that combine multiple words and are longer than 15 characters.
WE SAY: So the FBI wants me to remember longer password made of several words ? How about a 256 bits Encryption 32 characters long Password that changes every time you need to login, it is only good for 7 seconds and you don't have to remember any words or phrases. Instead, you just type a 4 digits PIN in your Cell ?
