Study material
Security researchers have found that a password's length does more to protect it from automated guessing than adding symbols or numbers to a short one. A sixteen-character passphrase made of a few ordinary words is much harder to crack than an eight-character password stuffed with symbols, because every extra character multiplies the number of guesses an attacker has to try before finding the right one.
