Google has released today version 68 of the Chrome browser. It is the first version where Chrome will mark HTTP sites as “Not Secure.” We’ve known about this for quite some time, as Google mentioned that the feature would be included in a future release of the browser. This is the latest step in Google’s push to increase HTTPS adoption, with HTTP sites in Incognito mode marked by the label last October.

Additionally, HTTPS sites won’t be marked ‘secure’ any more. The move is very likely to ruffle some feathers as non-HTTPS site owners will have to deal with panicked end users who suddenly see a big red ‘not secure’ tag on the website. According to Cloudflare, nearly half of the top 1 million sites do not use or do not redirect users to an HTTPS version, meaning that a large number of users will probably see a “Not Secure” indicator next to most of the sites they visit after they update to Chrome 68.
