You can easily see in your browser what type of SSL (TLS) certificate your website uses, including whether it was issued by Let’s Encrypt. This guide shows how to check it in Google Chrome.
Check the certificate issuer in Chrome
- Visit your website via https:// in Google Chrome.
- Press Ctrl+Shift+I (capital i) on Windows, or Cmd+Shift+I on Mac, to open the browser’s developer tools. You may need to reload the page afterwards.
- Select the Security tab to see what kind of SSL certificate your website is secured with.
Why the page may still show as “Not secure”
If your page is shown as “Not secure”, you can also see the reason here — for example that the page contains images linked over http. The page loads over https, but if it still pulls in resources such as images via http, it is not fully secure and is reported as not secure.

Update these links in your website’s code or database. See our guide for WordPress if your website uses WordPress.
Another common cause in WordPress is custom HTML in one of your widgets that loads images via http. If so, update the URL directly in the widget.
