Overall Checklist

• I agree to the project's Developer Certificate of Origin
• The top-level JSON objects are sorted alphabetically
• There are no open pull requests for the same update

for password-rules.json

• The given rule isn't particularly standard and obvious for password managers
• Generated passwords have been tested from this rule using the Password Rules Validation Tool
• Information has been included about the website's requirements (eg. screenshots, error messages, steps during experimentation, etc.)
• The PR isn't documenting something that would be a common practice among password managers (e.g. minimal length of 6)

for change-password-URLs.json

• There is no Well-Known URL for Changing Passwords (https://example.com/.well-known/change-password)
• The URL either makes the experience better or no worse than being directed to just the domain in a non-logged-in state

For the password rules, I tested manually what special characters were supported.
