Introduction

While you're surfing the web, your browser does many things behind the scenes to make sure the websites you're accessing aren't putting you at risk. Granted, while there is only so much your browser can do to keep you safe, it's a good idea to pay attention to any warnings it sends your way.

One of the errors you may encounter while using Google Chrome on a Windows PC or a Mac is a "Your connection to this site is not secure" warning. Initially, this may seem concerning as its wording implies that your security is at risk. However, this error can appear even on websites we know to be 100% secure and are confident in. This is due to an issue with security certificates, and many times is not the fault of your computer or your web browser at all. These certificates are what websites use to prove they are who they say they are on the internet, and if your browser detects an issue with a certificate, it will issue a warning.

This guide will help you determine whether this warning is being triggered by incorrect settings on your computer or web browser, or if the issue is with the website itself.

Chrome website is not secure

1 Make Sure Date and Time are Correct

Security certificates are used by our web browsers and computers to make sure a particular site is safe. Think of it as a form of ID. A website having a valid security certificate lets your browser know that the website claiming to be your bank is actually your bank, and so on. Just like our own government issued IDs have expiration dates, so do security certificates. If your computer has the wrong date and time set, this can cause certificates to appear invalid & your web browser will begin to issue security warnings.

If you notice that the Date and Time is continually incorrect even after manual adjustment, your machine may need to be serviced to replace its CMOS battery.

Verify the Date and Time on a Mac

  1. Select the time display in the top-right corner of your screen.
  2. Make sure both the date and time are correct.

  5. Enter your username and password, then select Unlock.

3 Try the Webpage Again

With your browser's website data removed, try to visit the website again. If you still receive security warnings, the issue is with the website itself, and not your device or its web browser. In this case, there is nothing you can do to resolve the error. Once the website owner/manager resolves the issue, you will stop receiving security warnings when you visit the website.
