How to Disable Incognito Mode in Chrome Windows and Mac?

Browsers allow surfing the internet with two different modes. One is a normal mode in which the browser will record all browsing history for speeding up your activities. Second is a private mode in which no history is recorded. Private mode will help you to keep your browser clean and not leaving any trace behind your history. Although it seems completely safe for the end users, but your activity is still accessible for computer administrator, your internet service provider and the websites you visit.

Microsoft Edge refers the private mode as InPrivate, Firefox calls it as Private and Google Chrome calls it as incognito mode. You can press “Control Shift + N” in Windows or “Command + Shift + N” in Mac to open an incognito window in Google Chrome.

Why to Disable Incognito Mode?

In our earlier article, we have explained how to open Chrome by default in incognito mode. However, there are situations you would like to disable the private browsing mode. For example, you may share your personal computer with your kids for browsing. You neither want them to use incognito mode nor delete the browsing history. Though annoying for the kids, you may need these types of parental controls on certain occasions.

In addition, administrators can disable the incognito mode to force users to browser only using normal mode.

Conclusion

Incognito mode not only allows browsing without storing history but also disables all extensions and cookies. Whenever you feel Chrome is loading slowly, the first option you need to check is to open the websites in incognito or guest mode. This will help to identify if there are problems with installed extensions. Disabling incognito mode though help in limit the access, you should not disable it unnecessarily. This is also the reason Chrome does not provide this option in settings.
