Chrome 68 will mark all HTTP sites as not secure
Heads up! Time to move to HTTPS, since the release of Chrome 68 all HTTP sites will be flagged as “not secure”
For the past several years, we’ve moved toward a more secure web by strongly advocating that sites adopt HTTPS encryption. And within the last year, we’ve also helped users understand that HTTP sites are not secure by gradually marking a larger subset of HTTP pages as “not secure”. Beginning in July 2018 with the release of Chrome 68, Chrome will mark all HTTP sites as “not secure”.
