Since February, Google has planned to brand non-HTTPS sites as "Not Secure," and today, with Chrome 68, that change is being rolled out to a wide audience.

With the change, every site now gets a label in its address bar: "Secure" if the site is loaded over HTTPS, "Not Secure" otherwise. In September, Google will make another change and remove the "Secure" label, marking the transition to a world where secure HTTP is the default rather than the exception.
