Check Chrome's connection to a site
You can see details about a website, your connection to it, and your visit history. Chrome will alert you if it can't establish a secure connection with the site.
- Open a site in Google Chrome.
- In the address bar in the top left, click the lock icon
or page icon
.
- Click the Connection tab.
- Depending on the site, you'll see two or three sections of information and a summary at the top highlighting important issues.
or page iconHere’s what each icon means and how to handle errors.
Site identity information
These icons let you know whether or not a sites uses TLS (Transport Layer Security) or SSL (Secure Sockets Layer) certificates to prove it's the site it claims it is with Chrome. You can tell if a site is real if it has a valid TLS/SSL certificate. Invalid certificates could mean that someone is trying to tamper with your connection to the site.

The site's certificate is valid and its identity has been verified by a trusted third party.
The site hasn't provided the browser with a certificate. This is normal for regular HTTP sites because certificates are usually provided only if the site uses SSL. Look in the address bar for the webpage icon 
Google Chrome can see the site’s certificate, but the site uses a weak security setup (SHA-1 signatures), so your connection might not be private.
Proceed with caution. These are common mistakes in websites' configurations, but that doesn't guarantee that your connection is secure.
Google Chrome knows there are problems with the site's certificate. Proceed with caution, because someone on your network (like someone sharing your wi-fi connection) might be messing with the website. If you disclose any information on the website, the person on the network might be able to read it.
Connection information
These icons let you know whether Chrome has a secure connection with the site you're on.
Green lock icon
Google Chrome has established a secure connection with the site you're viewing.
Your connection to the site isn't encrypted. This is normal for regular HTTP sites. Look for the address bar for the webpage icon
Your connection to the site is encrypted, but Google Chrome has found something on the page that could be unwanted images or ads. We suggest you don't enter private or personal information on this page.
Your connection to the site is encrypted, but Google Chrome has detected mixed scripting. Be careful if you're entering personal information on this page.
Mixed scripting is when a page served over HTTPS loads content over HTTP. It can provide a loophole for someone to take over the page. This could be third-party scripts or videos embedded on the page.
"Your connection is not private"
If you see an SSL error message saying "Your connection is not private," it means your Internet connection, or your computer, is stopping Chrome from loading the page securely. Learn how to troubleshoot an SSL warning.
