Those are the defaults for the little authentication management app I wrote a year and a half ago... Defaults are NIST guidelines, with options to implement "typical" adjustments, like rotation requirements. Default min-length is 12 iirc, and does a check against zxcvbn and the haveibeenpwned list. zxcvbn is displayed/advisory by default, can be set to required and the pwned list is enfoced, but can be toggled off.

Also, use of the term "passphrase" instead of "password" and recommending a short sentence with multiple words, casing, spacing and punctuation.
