From October 2017, the company will tag web pages that include login or credit card fields with the message “Not Secure” if the page is not served using HTTPS, the secure version of the internet protocol.
Quick Start: Have a search box or form on your website that runs over HTTP? You might want to switch your pages over to HTTPS by October.
What is the new update: Starting October 2017, Chrome (version 62) will show a “NOT SECURE” warning when users enter text in a form on an HTTP page, and for all HTTP pages in Incognito mode.
Description: Google has announced new efforts within Chrome to encourage webmasters and site owners to move their sites to HTTPS. Later this year, Google’s Chrome browser will show a warning message on pages that have search boxes or forms to fill out.
Google said, “[in] October 2017, Chrome will show the ‘Not secure’ warning in two additional situations: when users enter data on an HTTP page, and on all HTTP pages visited in Incognito mode.”
Here is the timeline for this Chrome launch:
Chrome recently added that pages with logins are required to be over HTTPS and even sent out webmaster warnings about the change.
Ultimately, Google wants to mark any web page over HTTP as insecure — but that will take them some time to accomplish.
Fixes: We will need to change the site to either use HTTPS for the entire site (ideal) or redirect the browser window to an HTTPS page containing the login form. Adding SSL to website will fix the issue and will sync with upcoming update.
