Moving towards a more secure web

Chrome currently indicates HTTP connections with a neutral indicator. This doesn’t reflect the true lack of security for HTTP connections. When you load a website over HTTP, someone else on the network can look at or modify the site before it gets to you.
A substantial portion of web traffic has transitioned to HTTPS so far, and HTTPS usage is consistently increasing. We recently hit a milestone with more than half of Chrome desktop page loads now served over HTTPS. In addition, since the time we released our HTTPS report in February, 12 more of the top 100 websites have changed their serving default from HTTP to HTTPS.
Studies show that users do not perceive the lack of a “secure” icon as a warning, but also that users become blind to warnings that occur too frequently. Our plan to label HTTP sites more clearly and accurately as non-secure will take place in gradual steps, based on increasingly stringent criteria. Starting January 2017, Chrome 56 will label HTTP pages with password or credit card form fields as "not secure," given their particularly sensitive nature.
We will publish updates to this plan as we approach future releases, but don’t wait to get started moving to HTTPS. HTTPS is easier and cheaper than ever before, and enables both the best performance the web offers and powerful new features that are too sensitive for HTTP. Check out our set-up guides to get started.
