Overall Checklist

• [x] I agree to the project's Developer Certificate of Origin
• [x] The top-level JSON objects are sorted alphabetically
• [x] 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 shared-credentials.json

• [x] There's evidence the domains are currently related (SSL certificates, DNS entries, valid links between sites, legal documents etc.)
• [x] If using shared, the new group serves login pages on each of the included domains, and those login pages accept accounts from the others. (For example, we wouldn't use a shared association from google.co.il to google.com, because google.co.il redirects to accounts.google.com for sign in.)
• [x] If using from and to, the new group, the from domain(s) redirect to the to domain to log in.

for shared-credentials-historical.json

• [x] You believe that the domains were associated at some point in the past and can explain that relationship

Hi! Can you provide some evidence, even a sentence, that these websites are sharing credentials?

Hey, Ricky! If you go directly to simplifimoney.com, it actually redirects to quicken.com. But then if you choose to sign in to Simplifi Money from there, you're directed to app.simplifimoney.com. But then there, the login field is in an iframe with quicken.com as the domain.

As always, thanks @carlylemiii!
