With the release of Chrome v62 in less than 3 months, Google will begin marking non-HTTPS pages with text input fields—like contact forms and search bars—and all HTTP websites viewed in Incognito mode as “NOT SECURE” in the address bar. The company has started sending out warning emails to web owners in August as a follow-up to an announcement by Emily Schechter, Product Manager of Chrome Security Team, back in April.
Google began marking sites in Chrome v56, which was issued in January of this year. They targeted HTTP sites that collect user passwords and credit card details.
For website owners to secure the information being shared among their visitors and their web server, they must start incorporating an SSL certificate. Failing to do this is risky for both parties: sites that allow the sending of information in clear text may also allow its exposure through the Internet.
