Chrome helps you browse more securely by alerting you when it detects a site that may be unsafe to visit. When a site may be unsafe, Chrome changes the icon next to the site address.
- In Chrome, open a web page.
- To check a site's security, to the left of the web address, check the security status symbol:
- Default (Secure)
- Info or Not secure
- Not secure or Dangerous
- To find a summary of the site's privacy details and permissions, click the icon.
- If you want Chrome to ask you before you use an unsecured connection, turn on HTTPS-First Mode.
- When HTTPS-First mode is on, if a site doesn't support HTTPS, Chrome displays a “Connection is not secure” warning. Learn how to turn on HTTPS-First mode.
What each security symbol means
These symbols indicate whether Chrome has or hasn’t established a secure and private connection with a site.Default (Secure)
Information you send or get through the site is private between you and the site.
Even when connected to a site securely, always be careful when you share sensitive or personal information. Check the site name in the address bar to make sure you're on the site you want to visit.
The site doesn’t use a private connection. Someone may be able to view and change the information you send and get through this site.
To resolve this issue, the site owner must secure the site and your data with HTTPS.
We suggest you don't enter any private or personal information on this page. If possible, don't use the site.
Not secure: Proceed with caution. Something is wrong with the privacy of this site’s connection. Someone might be able to find the information you send or get through this site.
Dangerous: Do not use this site. If you get a full-page red warning screen, the site has been flagged as unsafe by Safe Browsing. The site can misuse or abuse any information it receives, and could potentially attempt to install harmful software on your computer. When you use this site, it puts your privacy and security at risk.
Chrome authenticates and secures HTTPS connections with website certificates. These certificates encrypt the link between a site and your browser.
The Chrome Root Program lists the root certificates trusted by Chrome to authenticate HTTPS sites. Learn more about the Chrome Root Program.
Chrome will add custom root certificates from the certificates used by your computer’s operating system. To review the certificates on your device:
- On your computer, open Chrome .
- At the top right, click More Settings.
- Click Privacy and Security Security.
- Under “Advanced,” click Manage Device Certificates.
