Do you think your password is strong?

Do you think your password is strong?

The password basically is combination of letters, numbers and special characters 

The difficult passwords are using (upper case, lower case, numbers & Symbols).

If someone able to guess your password, then you've got a real problem !

So let us calculate how many possible choices in the most difficult passwords (26+26+10+ 33+ spacebar) and based on the password length we can figure out the total possible combinations.

Possible choices ^ Password length = total possible combinations.

With 8 characters password length (96) ^ (8) = 7.2 Quadrillion possible combinations

However, today this is wholly inadequate. 

Even though that 96 character data set yields 7.2 Quadrillion possible combinations, 

the attacker just needs high-speed processors in order to crack it.

Because the high speed of the graphic cards a PC using multiple Radeon graphic cards interface as a CPU, can generate 350 billion passwords/sec, and 7.2 quadrillion combinations in less than 6 hours and this is PC not a supercomputer :(

Interesting!

Here some tips for strong password,

? Contains at least 10 or more characters (upper& lower case, numbers& special characters).

? Don’t use the same password for business accounts and personal accounts.

? Create individual passwords for each and every account.

? Don’t change passwords with incremental variations such as pass1, pass2, etc.

? Don’t use dictionary words at all even if long ones or ever in backward spelling.

? Don’t use common sequential order for letters or numbers such as abc or 123.

? Don’t use repetitive letters or numbers such as BBB or 444.

? Don’t use continuous characters on the keyboard such as zxc or qwe.

? Don’t use common substitutions such as “@” for A or “!” for “i”.

? Don’t use any portion of your name, birthdate, company, product line of the company :) or any other personal information; or any personal information for your close family and friends.

And then all you need is a supercomputer to keep track of all your passwords.
