 When contributing or amending a set of websites sharing a credential backend, you should state why you believe the relevant domains do or do not share a credential backend, with evidence to support your claim. This may involve WHOIS information or content served from the domains themselves.
 
-[`quirks/websites-with-shared-credential-backends.json`](quirks/websites-with-shared-credential-backends.json) contains a lower fidelity version of the data in [`quirks/shared-credentials.json`](quirks/shared-credentials.json) and [`quirks/shared-credentials-historical.json`](quirks/shared-credentials-historical.json). It must be regenerated using [`tools/convert-shared-credential-to-legacy-format.rb`](tools/convert-shared-credential-to-legacy-format.rb) whenever those files are changed.

 ### Contributing a Change Password URL
 
 Use the website in question until you find the standalone page for updating the user's password, or a high-level "Account Information" or "Security" page. The closer the URL takes the user to be able to change their password, the better. Before adding a URL, ensure that it works properly both when the user is logged in and when they are not. URLs added to [`quirks/change-password-URLs.json`](quirks/change-password-URLs.json) should have a scheme of https unless the website does not allow changing the password on an https page.
