As a start it should be clear that a 100% secure password doesn`t exist. It doesn`t matter how long or complicated the password is. It s always a matter of resources (processing power of the CPU and time), which can be applied by the attacker. However, the methodology that is presented here, can create really strong passwords. In the following example an attacker would need approximately 429 billion years in order to break the password.
A secure password should consist of the following elements:
- At least 9 characters: The more characters that someone uses, the more combinations should an attacker try
- You should have small and capitals letters, special signs and digits: This also increases dramatically the number of the possible combinations
The password should under NO circumstances consist of:
- Name or keyword: Ideally, the letters that you should use, should make no sense
- Typical combinations: For example 012345678 as a password would not be secure
- Your birthday, or any number which can be traced back to you
How can I create a secure password that I can remember?
A simple way is to use some lines from a famous song or phrase. For example, the line from a Christmas song: Jingle bells, jingle bells, jingle all the way. From that phrase we keep the first letter of every word and we create a new word.
So, from “Jingle bells, jingle bells, jingle all the way” it becomes Jbjbjatw
Now we need a number that is related to that phrase. As we celebrate Christmas on 25 December we are going to use the number 2512. We put the 25 at the beginning and the 12 at the end of the password.
Now the password is: 25Jbjbjatw12
The last thing that is missing now is the special sign. We are going to use the first letter of a colour which we think that goes with our phrase. In this case, the colour red (Santa`s clothes) with the special sign #.
The final result for our password is: 25Jbjbjatw12#r
Finally, it would be wise to write down the password in a piece of paper. In order for only you to know what it means, do not write the last result of the password, but only something that will remind you of it. Our example could have the following note:
25Jbjbjatw12#r à do not forget that 25 December is Christmas and we sing jingle bells and Santa wears red clothes.
Resistance of the password
One website where you can test how strong your password is, is the web app: HowSecureIsMyPassword. According to that webpage a computer would need 429 billion years to break the code 25Jbjbjatw12#r. This is 28 times more than our universe exists. Nonetheless, this password will eventually break.
