HTTPS has largely replaced its less secure predecessor HTTP as the default choice for sending resources over the internet. The key difference between the two is that HTTPS transmits data using an encrypted connection, while data loaded over HTTP is not. Google began marking all sites still utilizing HTTP connections as 'Not Secure' with the release of Chrome 68 last year, and today, Google announced additional plans to inform users when sites utilize an insecure connection. With these latest changes, the Chrome team hopes to address the problem of mixed content.
