Since its version 56 of Chrome, Google is marking HTTP pages as « Non secure », if they have password or credit card fields. We wrote an article about it on November 18th.
With Chrome 62, these warnings will be extended to all pages where users enter personal data, and to every HTTP page visited in Incognito mode. According to Google, passwords and credit cards data are not the only confidential data. Actually, all private data entered into a website should remain confidential.
Google points out that it plans to mark every HTTP page as “Non secure”, even when the browser is not in Incognito mode.
