Introduction

Security warnings while browsing can be frustrating. In many cases, they are caused by a website that's not configured properly, but there are a few computer and Chrome browser settings we can check to ensure the problem isn't happening because of a mistaken setting.

This guide will take you through the basic settings to ensure your computer and Chrome aren't the cause of these security errors. We will check:

  • Computer date and time
  • Chrome cache and cookies
Chrome security warning.

A Quick Fix

One quick way to correct this issue may involve your antivirus. You can temporarily disable your antivirus to test it if was blocking access to the website.

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. If the date and time are wrong, certain web pages may give security warnings and secure programs such as work VPNs, banking apps, and most social network apps will not function. Since iOS devices (iPhones and iPads) and Android set their time automatically, you don't usually need to check those.

If you notice that your Date and Time keeps becoming unsynced, you should speak to the manufacturer about replacing your CMOS battery.

How to 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.
    Mac Menu Bar with time menu and date highlighted.
  3. If the time is incorrect, select the time display in the top-right corner of your screen, then select Open Date & Time Preferences.

  5. Enter your username and password, then select Unlock.
    Unlock prompt with user name, password, and unlock button highlighted.
  6. In most cases, letting your Mac take care of setting the time is the best choice. Make sure there is a check for Set date and time automatically, and make sure a time server close to you is chosen.
    Date and Time preferences with Set date and time automatically highlighted.
  7. If you want, you can set the time manually. Remove the check for Set date and time automatically, then enter the correct date and time. Press Save when done.

3 Turn Off Problematic Chrome Extensions

Extensions provide extra features to Chrome. Sometimes they aren't coded well or they break after a Chrome update and begin to cause problems. Disabling or removing unneeded or unwanted Extensions can help resolve these problems.

Using Incognito Mode, See if Disabling Extensions is Needed

  1. Open Google Chrome.
    Google Chrome
  2. Click the menu button.
    The menu button on the right side of Chrome
  3. Select the New Incognito Window.

4 Clear History and Cached Browsing Data

If you're still having issues 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 Google Chrome.
    Google Chrome.
  2. Select the menu at the top.
    Menu button highlighted and pointed out in Google Chrome.
  3. Click More tools, then select Clear browsing data.
    Chrome menu with More Tools and Clear Browsing Data highlighted.
  4. Select Advanced at the top. For Time range, select All time. Place a checkmark next to each item you'd like to clear, then select Clear data. We recommend selecting everything we've shown here except passwords and autofill form data.

5 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.
