October 18, 2024Is it safe to check my passwords using Have I Been Pawned?
Short answer is yes, because it never sends your password anywhere. It makes a SHA1 hash of your password, sends the first few characters of that hash, and receives a list of all the hashes which match those characters (which will generally be a few hundred matches), and then your browser picks out the correct one and shows it to you. If you don't trust the website, you can do the same process yourself: Use an open source tool you trust to create a SHA1 hash of the password you want to test. In a web browser, go to https://api.pwnedpasswords.com/range/(first 5 characters of your hash) Find the rest of your hash in the list, the number after the colon is the number of instances found. If it's not in the list, that's good news! You haven't been pwned. Example: Using a command line tool, the SHA1 hash of 'password' is 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8 So we navigate to: https://api.pwnedpasswords.com/range/5baa6 And in that list we find the entry that starts with 1e4c9b...., and look after the colon to find that it's been used 3645804 times and is therefore probably not a very good password.

April 19, 2019Password Strength Recommendations for 2023?
Regarding dictionary words, when there are enough of them they can make a very secure passphrase. E.g., I use diceware for passwords that need to be strong but can't be stored in a password manager. For 2FA, consider FIDO2 for phishing resistant 2FA or even going passwordless. Can't phish what isn't there :) More on reddit.com

r/cryptography on Reddit: How secure is my password?
October 18, 2024 -
I used LUKS to encrypt a USB. The passphrase I'm using is 25 characters and it's a combination of different random words. Then I would use "L33t speak" to change around certain letters to produce a combination of numbers letters and special characters. As an example I would change the word "boys" into "30y3". Is this a safe practice? I would use a password generator, but those are difficult for me to remember and I don't feel comfortable using copy and paste.

Use a natural language Diceware passphrase . It alternates adjectives and nouns so the passphrase is more memorable while still remaining secure. EG, "yawning laptops smug dentists sleazy light mime"
