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 Microsoft Edge on a Windows PC or a Mac is a "Not Secure" or "Not Private" 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.

Page problems on Microsoft Edge.

1 Make Sure the 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.

2 Clear Cache and History on Edge

After verifying that the date and time on your device is correct, test things again. If you're still having issues with security warnings on a particular website, your browser could be holding onto some outdated or bad data in the form of an old cookie, cached version of the website, etc. Clearing this data allows your browser to load the website freshly as if it had never been there before.

  1. Open Microsoft Edge, select the Menu, point to History, and select Clear browsing data.

    Site permissions
    Personal Choice Some sites will ask permission to use your microphone or video camera, and the Edge browser remembers this. If you clear this option, the browser will prompt you again for access the next time you visit; it's safe to clear this option.
    Hosted app data
    Personal Choice Some sites, such as webmail, document editing, or enterprise management tools load entire app data to the browser. If the site you're having problems with uses exceptionally complex tools, it may help to clear hosted app data, otherwise it's fine to leave this unchecked.

3 Try Again or Carefully Bypass Warnings

You have made sure the date and time settings are correct on your computer, and cleared your cache. Try browsing the page you were having problems with again.

If you continue to have difficulties, it means there is a problem with the way the website itself is configured, not with your computer. This is not a problem you can fix with settings or options, but rather will require the people who made the website to change how it functions.

Please contact the product manufacturer for further assistance.

Carefully Bypass Certain Warnings

Sometimes it is possible to bypass the "Your connection isn't private" warning and view the page in some situations.

If the Edge browser is warning you about the security on a page, it is doing so for a good reason. There is a high chance of someone snooping or watching what you are doing on the site.

Because of this, should you choose to continue, do not input any secure information into the site. Including:
  • Do not put in usernames or passwords
  • Do not put in any personal information such as name or address
  • Do not put in your email address
A common exception to this is local tools. Some routers and other networking hardware use a self-signed certificate, meaning the router or device itself is the 'authority' that vouches for the content. On a local network, this is fine and understandable (you don't have a separate computer on your network just to certify your router's control website) and it is safe to bypass this warning and log into your router or device.
  1. On the warning screen, select Advanced.
