I use software that uses Auth0 at least to validate passwords. As listed on this page: https://auth0.com/docs/connections/database/password-options#personal-data,
users can be forced to avoid certain words in their password. Using the example on the page, as of now we couldn’t use the word “John” in a password but we could use joHn in a password.
Can validating a password be (custom) changed to have it avoid John whether a letter in that word is in lower case or in upper case? So “joHn” would be avoided as well?
