unecure site

If sites that previously worked now show as not secure on a new computer, the browser is indicating that the connection or certificate is not valid.

In Microsoft Edge, check these items:

1. Open the site and look at the address bar.
   • A secure site shows a padlock icon.
   • A site that is not secure may show Not secure, a warning triangle, or no padlock.
2. Click the icon in the address bar.
   • This shows whether the connection is secure and certificate details.
3. If the site is using HTTP instead of HTTPS, avoid entering passwords or personal information.
   • HTTP sends data in plain text.
   • HTTPS encrypts the data.
4. If Edge warns that the certificate is invalid, expired, or self-signed, avoid using the site for sign-in or sensitive data.
   • Microsoft Edge recommends not entering personal information on those sites.
5. Check Edge security warnings settings:
   • Open Microsoft Edge.
   • Select Settings and more > Settings > Privacy, search, and services > Security.
   • Make sure Get alerts about insecure connections is turned on.
   • Review whether Edge is alerting only for insecure public sites or for both public and private sites.
6. If the issue is only on support.microsoft.com sign-in pages and the sign-in keeps looping, check Trusted Sites settings.
   • These sites should not be partially mixed in the Trusted Sites list.
   • If any are in Trusted Sites, all related Microsoft sign-in domains must be included together for cookie sharing to work.

If the site is a local device page such as a router or internal site, Edge can warn because those pages may still use HTTP or an invalid certificate.
