Check if a site’s connection is secure
To see whether a website is safe to visit, you can check for security info about the site. Chrome will alert you if you can’t visit the site safely or privately.
- Open a page in Chrome on your computer.
- To check a site’s security, to the left of the web address, look at the security status:
- Info or Not secure
- Not secure or Dangerous
- To see the site’s details and permissions, click the icon. At the top of the panel, you’ll see a summary of how private Chrome thinks the connection is.
What each security symbol means
These symbols let you know how safe it is to visit a site. They tell you if a site has a security certificate, if Chrome trusts that certificate, and if Chrome has a private connection with a site.
The site isn’t using a private connection. Someone might be able to see the information you send through this site. We suggest that you don’t enter sensitive details, like passwords or credit cards.
On some sites, you can visit the private version of the page:
- Select the address bar.
http://, and enter
If that doesn’t work, contact the site owner to ask that they secure the site and your data with HTTPS.
Fix “Your connection is not private” error
If you see a full-page error message saying “Your connection is not private,” your Internet connection or your computer isn’t letting Chrome open the page securely. Learn how to troubleshoot “Your connection is not private” errors.
What a security certificate is
When you go to a site that uses HTTPS (connection security), the website’s server uses a certificate to prove the website’s identity to browsers, like Chrome. Anyone can create a certificate claiming to be whatever website they want.
To help you stay on safe on the web, Chrome requires websites to use certificates from trusted organizations.
