Reliable Strength Test for Master Password

They are clearly making some different assumptions. By raw brute force this would take a while. But these are two dictionary words with common letter to number substitutions and no special characters. A wordlist plus mutations (o->0, l->1, etc) would make this a lot faster than raw brute force. I personally feel that Aband0nedFairgr0und is about as secure as AbandonedFairground which is easily taken care of by running a dictionary attack with two words against this. The first link seems to only use brute force estimation because it doesn't flag your result lower when you use a word like password instead of random letters like akdudlqu. More on reddit.com

Safe: Check the strength of password

Cool. What would be the difference to https://github.com/nbutton23/zxcvbn-go ? I wrote a small usage example here, which colors the password prompt relative to it's strength: https://github.com/chzyer/readline/blob/ccd7589339d9a8a8dc637490854729762e200c8a/example/pass_strength/pass_strength.go More on reddit.com

Password strength

correcthorsebatterystaple is a safe type of password. You don’t need special characters except to pass stupid “strength” tests.

The real question is: Where do you store all your never-reused passwords? The correct answer is: In a password manager. And that makes your question unimportant since the password manager generates strong random passwords, no thinking required.

r/sysadmin on Reddit: Reliable Strength Test for Master Password

December 31, 2022 -

In light of the recent LastPass breech I looked at different strength test websites to see how long a password would hold up under a offline brute-force attack.

The password I tried was: Aband0nedFairgr0und

This is a a 19 character password with a combination of uppercase/lowercase/numbers (no special characters)

I went to 5 different password strength sites and they all give me wildly different results for how long it would take to crack.

https://www.security.org/how-secure-is-my-password/	9 quadrillion years
https://delinea.com/resources/password-strength-checker	36 quadrillion years
https://password.kaspersky.com/	4 months
https://bitwarden.com/password-strength/	1 day

As you can see the results are all over the place!

Can anyone recommend the best/ most upto date resource to check password strength. I am sure people with bitcoin mining farming GPUS can crunch 100s of guesses per second.

PS: Dont worry, Aband0nedFairgr0und is not a password I use and was made up as a test.

They are clearly making some different assumptions. By raw brute force this would take a while. But these are two dictionary words with common letter to number substitutions and no special characters. A wordlist plus mutations (o->0, l->1, etc) would make this a lot faster than raw brute force. I personally feel that Aband0nedFairgr0und is about as secure as AbandonedFairground which is easily taken care of by running a dictionary attack with two words against this.
