When you connect to a website, Google Chrome can show you details about your connection and alert you if it’s unable to establish a fully secure connection with the site. Learn about Google Chrome’s security settings.

See if the site is using a secure connection (SSL)

If you’re entering sensitive personal information on a page, look for a lock icon to the left of the site’s URL in the address bar to see if the site uses SSL. SSL is a protocol that provides an encrypted tunnel between your computer and the site you’re viewing. Sites can use SSL to prevent third parties from interfering with the information traveling through the tunnel.

Icon What it means
globe The site isn’t using SSL. Most sites don’t need to use SSL because they don’t handle sensitive information. Avoid entering sensitive information, such as usernames and passwords, on the page.
Lock icongreen https Google Chrome has successfully established a secure connection with the site.Look for this icon and check the URL if you’re required to log in to the site or enter sensitive information on the page.If a site uses an Extended Validation SSL (EV-SSL) certificate, the organization’s name also appears next to the icon in green text. Make sure the browser is set to check for server certification revocation to identify sites with EV-SSL certificates.
alert iconyellow https The site uses SSL, but Google Chrome has detected insecure content on the page.Be careful if you’re entering sensitive information on this page. Insecure content can provide a loophole for someone to manipulate the page.
alert iconred https The site uses SSL, but Google Chrome has detected either high-risk insecure content on the page or problems with the site’s certificate. Don’t enter sensitive information on this page. Invalid certificate or other serious https issues could indicate that someone is attempting to tamper with your connection to the site.

See more details about the site

Click the globe icon or the lock icon to see even more details about the site’s identity, your connection, and your visit history for the site.

Site identity

Sites using SSL present security certificates to the browser to verify their identity. Anyone can set up a website pretending to be another site, but only the real site possesses a valid security certificate for the URL you’re trying to reach. Invalid certificates could indicate that someone is attempting to tamper with your connection to the site.

Icon What it means
green lock The site’s certificate is valid and its identity has been verified by a trusted third-party authority.
orange alert The site has not provided the browser with a certificate. This is normal for regular HTTP sites (look for the globe icon in the address bar), because certificates are usually provided only if the site uses SSL.
red lock Google Chrome has detected problems with the site’s certificate. You should proceed with caution because the site may be pretending to be another site in order to trick you into sharing personal or other sensitive information with them.

Your connection to the site

Google Chrome lets you know whether your connection is fully encrypted. If your connection is insecure, third parties might be able to view or tamper with the information you provide on the site.

Icon What it means
green lock Google Chrome has successfully established a secure connection with the site you’re viewing.
orange alert Your connection to the site is not encrypted. This is normal for regular HTTP sites (look for the globe icon in the address bar).
gray alert Your connection to the site is encrypted, but Google Chrome has detected mixed content on the page.Be careful if you’re entering information on this page. Mixed content can provide a loophole for someone to manipulate the page. This content could be third-party images, videos, or ads embedded on the page.If you’re connected to the Internet via a public wireless network, mixed content is especially risky because wireless networks are easier to tamper with than wired networks.

Visit history

This will show if you’ve ever visited the site before. However, if you’ve cleared cache and cookies, the visited history is also cleared

Icon What it means
blue alert You’ve visited the site before, so chances are you trust this site.
orange alert You’ve never visited this site before. This message is normal if you know this is true. However, if the site looks familiar and you didn’t clear your browsing history recently, it may be pretending to be another site. Please proceed with caution.
