   This is scientific American sixty seconds science, I'm Christopher Taliyatah. Got a minute?


  When you think of an password for yet another online account, longer is better. Right? Well, it's true if your password is just strings 1 and radoms of numbers and symbols. But the use of memerable phrase as some sites recommoneded, your super-long password would be twice as easy to crack, assuming the password-crackers 2 knows the grammar. Researchers have created grammar-smart * and set them at 144 paasswords, each of the phrase set as 18 characters long. 2 and half trilience * later, they cracked quarter of them. And the Odward decoded 3 dozens password stated air-crackers could not. Researchers have presented their programs at the conference on data and application security and privacy, or code spy. The best password crackers could guess 33 billion times a second. Using standard grammars cuts down the off-number * possibilities and time it used to crack your password. To avoid the pronouns and verbs, the researchers say, it's easy to guess because there are fewer number, and adjectives and nouns. For example, she blanks me with science is a weaker password than three blinds mine sprine . See how the hackers 4 run.
  Thanks for the minute, for scienctific america, sixty seconds science. I'm Christopher Taliyatah.
