Is xkcd Password Strength true?
For example, passwords are often measured in bits of entropy, but there’s a strong argument to be made that bits are the wrong metric to determine password strength. In our example xkcd comic, 44 bits of entropy is estimated to take 550 years to brute force.

Is password length better than complexity?
According to guidance offered by the National Institute of Standards and Technology (NIST), password length is more important than password complexity. This actually makes a lot of sense as longer passphrases take longer to crack, and they are easier to remember than a string of meaningless characters.
What is the Schneier scheme?
There’s still one scheme that works. Back in 2008, I described the “Schneier scheme”: So if you want your password to be hard to guess, you should choose something that this process will miss. My advice is to take a sentence and turn it into a password. That nine-character password won’t be in anyone’s dictionary.
What is a good example of a strong password?
An example of a strong password is “Cartoon-Duck-14-Coffee-Glvs”. It is long, contains uppercase letters, lowercase letters, numbers, and special characters. It is a unique password created by a random password generator and it is easy to remember. Strong passwords should not contain personal information.
What are the NIST password requirements?
NIST now requires that all user-created passwords be at least 8 characters in length, and all machine-generated passwords are at least 6 characters in length. Additionally, it’s recommended to allow passwords to be at least 64 characters as a maximum length.
What is entropy in passwords?
Password entropy is a measurement of how unpredictable, and therefore un-guessable, a password is. Most of us don’t have passwords that pass the entropy test. For example, “123456” and “qwerty” were two of the top passwords used in 2021.
Does XKCD stand for something?
According to the xkcd FAQ, the name “xkcd” doesn’t stand for anything. In his Google-speech, Randall said that xkcd originated as a previously unused random 4 letter string which he used, e.g., as his account name on various internet services.

How is the password generation algorithm in xkcd?
xkcd’s password generation scheme requires the user to have a list of 2048 common words (log 2 (2048) = 11). For any attack we must assume that the attacker knows our password generation algorithm, but not the exact password. In this case the attacker knows the 2048 words, and knows that we selected 4 words, but not which words.
How does the xkcd password strength comic work?
The comic illustrates the relative strength of passwords assuming basic knowledge of the system used to generate them. A set of boxes is used to indicate how many bits of entropy a section of the password provides. The comic is laid out with 6 panels arranged in a 3×2 grid.
How many bits of entropy can you get from xkcd?
The xkcd strip suggests 11 “bits of entropy” per word, which can be achieved using a list of 211 = 2048 words. I scraped a list of 1949 words (close enough) from this site, which is based on the most frequent occurrences in newspapers.
