Ask Slashdot: How Do You Create A Highly-Secure Password? (securitymagazine.com)
An anonymous reader writes: A security lab at Carnegie Mellon performed a study on password security recently, and issued a warning about common user misconceptions. For example, 'ieatkale88' would require 4 billion more guesses than 'iloveyou', because 'iloveyou' is one of the most common strings in passwords. And the word 'pAsswOrd' would take 4,000 times more guesses than 'p@ssw0rd', simply because "In modern day password-cracking tools, replacing letters with numbers or symbols is predictable."
But then what passwords are secure in the face of these modern password-cracking tools? As professionals in the IT industry, what advice would you give?

#1. But I can't remember all those passwords.
- use a password manager
#2. But I like the formula I use. It's my name + the website name.
- no. Just use a password manager
#3. How will I know that my password isn't in a dictionary list?
- use a password manager and have it generate random passwords
#4. But I cannot remember long passwords.
- use a password manager
Also, "ieatkale88" can now be cracked in the same number of tries as "iloveyou" or "pAsswOrd" because they are now all added to common dictionaries.
Once you publish your "secure" password someone will add it to a dictionary.

Being strictly paranoid, how can I be sure that all passwords generated on the above site are not logged and added to lists checked by password crackers?
The first thing you need to do is stop listening to statistics someone else faked.
Of all the various ways in which attackers can gain passwords, only two involve cracking them (brute-force and cracking a password database). One of them should be a non-issue, because any software or service that doesn't protect against brute-force is fundamentally broken and shouldn't be trusted with your password anyway. Make your password "a", save everyone the trouble. For a password database crack, firstly the security of the server already failed, and then you're at their mercy a second time because if the password is stored unencrypted, you're fucked. If the password is stored hashed but not salted, you are pretty much fucked. And if the password is properly hashed and salted, congratulations you have the one scenario where a good password actually matters.
In all other attacks on your password, from phishing to shoulder-surfing and keyloggers, it doesn't matter how good your password is, how long it is or how complex it is.
So, if you are really so concerned about the one scenario that you are ready to type V9AnKH5Crpfukuy5gAFB till the end of your days, go to https://www.random.org/passwor... and fire it up. Because all the hints you find on making a "good" password are also known to the people writing password crackers and coded into the pertubation algorithms. True randomness is your best bet.
The one thing that matters, and there's an article about it but I'm too lazy to google it, is length. Length > Complexity. "aaaaaaaaaaaaaaa" is more secure than any variation of 8 characters ever will be, simply because, at least until this post, no password cracker would run the chain like a, aa, aaa, aaaa, ... to arbitrary length.
IMHO, and I am an expert in the field and given speeches about password security, forget all the "password complexity" rules, they are all bullshit. They're the safety net that makes sure that "password" is not a legal password on your system. But the world continuously invents better idiots, so "password1!" is and you're fucked anyway.
