Google officially announced version 68 of the Chrome browser today, formalizing its plans to fulfill its past pledge to mark all unencrypted (non-HTTPS) pages as “not secure.” This move comes nearly two years after Chrome announced its slow-burning plan to promote the use of secured (HTTPS) pages across the browser.

In previous updates, the browser had already begun to mark critical HTTP pages — like those that collect bank and personal information — as “not secure.” But to move toward its goal of assumed security on its browser, Chrome announced today that it plans to begin removing the “Secure” marker on HTTPS sites this September and begin marking all unencrypted sites with a red “Not secure” marker this October.
