This modification mostly follows the principles of Dan Wheelers password strength estimator zxcvbn. It does not weight password strength by their combination of upper/lower letters, special characters and numbers, but on how easy they are to crack in reality.

To increase the safety of your users account, you can force them to use passwords of a minimum length, minimum strength and even force them to exclude certain words from their passwords (like your site name, the topic your site refers to, etc.).

But the other side of the equation, is no matter how secure the password is, if it has been compromised not password strength estimator will help make it better. As such NIST has the following guidance: check passwords against those obtained from previous data breaches. Pwned Password integration does that.
zxcvbn Readme said:
zxcvbn is a password strength estimator inspired by password crackers. Through pattern matching and conservative entropy calculations, it recognizes and weighs 10k common passwords, common names and surnames according to US census data, popular English words, and other common patterns like dates, repeats (aaa), sequences (abcd), keyboard patterns (qwertyuiop), and l33t speak.

Consider using zxcvbn as an algorithmic alternative to password policy — it is more secure, flexible, and usable when sites require a minimal complexity score in place of annoying rules like "passwords must contain three of {lower, upper, numbers, symbols}".

Password reuse and credential stuffing

Password reuse is normal. It's extremely risky, but it's so common because it's easy and people aren't aware of the potential impact. Attacks such as credential stuffing take advantage of reused credentials by automating login attempts against systems using known emails and password pairs.


NIST's guidance: check passwords against those obtained from previous data breaches

The Pwned Passwords service was created in August 2017 after NIST released guidance specifically recommending that user-provided passwords be checked against existing data breaches . The rationale for this advice and suggestions for how applications may leverage this data is described in detail in the blog post titled Introducing 306 Million Freely Downloadable Pwned Passwords. In February 2018, version 2 of the service was released with more than half a billion passwords, each now also with a count of how many times they'd been seen exposed.
