Want to make super-password? that would be difficult dismantled your password? Say goodbye to the eight-character keyword (password) you Facebook. Now the era of 12 characters from online security has been with us, according to a report that was launched this week by the Georgia Institute of Technology.

Researchers use a graphics card groups group to solve the eight character password is less than two hours. However, when researchers use the same processing procedure with 12 character passwords, they find that it takes 17.134 years solved. “The length of your keywords in some cases can lead to vulnerabilities,” said Joshua Davis, a research scientist at the Georgia Tech Research Institute.

Hard to say what will happen in the future, but for now, 12 character password should be the standard, says Richard Boyd, a senior research scientist who also worked on the project. The researchers recommend the 12 character password – different from those who use 11 or, say, 13 characters – because the amount that produces a balance between “comfort and security.”

They assume a seasoned hackers will be able to try a billion combinations of passwords per second. on the scenario, it takes 180 years to break a password with 11 characters, but now there is a big leap when you add just one character – it takes 17.134 years.

Password is getting longer over time, and security experts have recommended that people use a whole sentence as their keyword. This is a password that is suggested – a statement from Carnegie Mellon University:

“No, not the capitol of Wisconsin Cheeseopolis!” (No, the capital of Wisconsin Is not Cheeseopolis!)

Or maybe something easy to remember, like this: “I have two children: Jack and Jill.” (I have two kids: Jack and Jill) But, not all sites will accommodate long keyword, said Boyd.

It is best to use the longest and complex keyword. For example, if a site allows you to create a keyword with non-letter characters – such as @ y;) v% W $ 5 “- should you use it.

There are only 26 characters in the English alphabet, but there are 95 letters and symbols on a standard keyboard. More characters means more changes in the composition, and it soon becomes more difficult for computers to extract the right keywords in a way only a guess.

Some sites allow for a keyword that is super long. The longest visits by Boyd on Fidelity.com, a financial site that allows to make a 32 character keyword. On the Microsoft site that cares for the security of your keywords, the technology giant revealed publicly created passwords do not make actual words or combinations of the logic of the letters. it makes you more secure than a “dictionary attack,” which make a database of words and general character sets in guessing the code.

Georgia tech researchers using the method of attack “brute force” when they determine that the key word should have a length of 12 characters. To do so, they created a computer graphics card, a cheap and reliable program to perform basic computing quickly.

Processors on graphics cards that run simultaneously, trying to guess all possible combinations of keywords. The more characters in the keyword the more guesswork is needed.

But if your keywords are very long, and many sites require a new keyword with periodically, how do you have to remember everything? “That is a real problem,” said Georgia Tech researchers.

However, There are several solutions.

A website, Password Safe, will store your keyword list, but Boyd and Davis said the hacker was able to get the list.

Another company sells tokens that must be carried about the owner of the keyword. This key chain-sized device parse the number of keywords at random a few times every minute, and the user must enter this amount and a shorter keyword to log in (go).

Some sites – Facebook for example – to market the log-in and user name as a way to access the site across the network. It is good for users but it is potentially dangerous because if hackers figure out a single password, they can access many sources of information, said the researchers.

Reason keyword must be kept long is that the computer and graphics card is faster, the researchers said Georgia’s technology.

“This is really – really cheap – only a few hundred dollars – and they will have a capacity that is compared with a super computer which only a few years ago,” Boyd said about the rapid process of picture cards.

Perhaps our brains will be bigger and faster, too. We so need some way to remember the keyword.
