How Good are My Passwords?

Post by rogerwimmer » Fri Aug 08, 2014 6:08 am

Doc: Is there a way for me to find out how good (secure/safe) my passwords are that I use for different websites and other things? Thanks. - Anonymous

Anon: There are several sites on the Internet that provide that information for you. One site has several options to use – click here.

NOTE: Don’t enter your real passwords. Enter something that contains the same number of elements, but not the real elements you use

The key to passwords is how many elements you include. Here is how that works. For each element, there are 95 possible choices (52 upper & lower case letters, 10 numbers, and 33 special characters). If you have a password only two elements long, there are only 9,025 possibilities (95 x 95). For each element you add, multiply the preceding total times 95. 3 elements = 857,375 possibilities, and so on. An 8 element password has 6.6 quadrillion possibilities.
