You can disable incognito mode through your browser settings, but the method depends on which browser you use

Incognito mode (called Private Browsing in Safari and InPrivate in Edge) prevents your browser from storing your search history, cookies, and temporary files. If you want to stop yourself or others from using it, you can restrict access through settings or parental controls. The steps differ between Chrome, Firefox, Safari, and Edge, and some methods work better on shared devices than others.

Disabling incognito is most useful on a family computer where you want to may support all browsing is recorded, or on a work device where your employer needs visibility into web activity. On your personal device, turning it off is less common — most people either use it intentionally or ignore it entirely.

Key Takeaways

  • Chrome, Firefox, Safari, and Edge each have different methods to disable incognito mode, and most require you to access browser settings or use parental controls.
  • On Windows and Mac, you can restrict incognito through parental controls at the operating system level, which affects all browsers at once.
  • Disabling incognito on a shared device prevents anyone using that device from hiding their browsing history from other users.
  • Some methods require administrator access to your computer, so a standard user account cannot re-enable incognito without the admin password.

Disable incognito in Google Chrome

Chrome does not have a built-in setting to disable incognito mode directly in the browser. Instead, you must use Windows Group Policy (on Windows) or parental controls (on Mac). On Windows, open Group Policy Editor by pressing Windows key + R, typing gpedit.msc, and pressing Enter. Navigate to User Configuration > Administrative Templates > Google > Google Chrome, then find the policy called "Incognito mode availability" and set it to "Disabled".

On Mac, you cannot disable incognito through Group Policy. Instead, use Screen Time (built into macOS) to restrict Chrome's access, or use a third-party parental control tool. If you are managing a work device, your IT department may push a policy through a mobile device management system that disables incognito across all browsers.

Disable incognito in Mozilla Firefox

Firefox also lacks a direct browser setting to disable private browsing. On Windows, use Group Policy Editor the same way as Chrome: open gpedit.msc, navigate to User Configuration > Administrative Templates > Mozilla > Firefox, and set "Disallow private browsing" to Enabled. On Mac, Firefox does not support Group Policy, so you will need to use parental controls or a third-party tool.

An alternative on any operating system is to edit Firefox's configuration file directly. Type about:config in the address bar, search for browser.privatebrowsing.autostart, and set it to True. This forces Firefox to open in private mode by default, though it does not prevent users from manually opening a non-private window. This method is less reliable than Group Policy because users can change it back.

Disable incognito in Safari

Safari's Private Browsing mode can be restricted on Mac through System Preferences. Open System Preferences, go to Parental Controls, select the user account you want to restrict, and check the box for "Disable private browsing." On iPad and iPhone, go to Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps, then toggle off Safari or restrict it further.

This method requires you to set up a Screen Time passcode, which prevents the user from changing the setting back without the code. If you forget the code, you will need to reset it through your Apple ID or contact Apple Support.

Disable incognito in Microsoft Edge

Edge uses the same Group Policy method as Chrome on Windows. Open Group Policy Editor, navigate to User Configuration > Administrative Templates > Microsoft Edge, find "InPrivate mode availability," and set it to "Disabled." On Mac, Edge does not support Group Policy, so use macOS parental controls instead.

You can also manage Edge through Microsoft Intune if you are using a work account synced to your device. This is the most reliable method for work devices because it prevents users from changing the setting even if they have administrator access.

Use parental controls at the operating system level

The simplest way to disable incognito across all browsers at once is to use your operating system's parental controls. On Windows 10 and 11, open Settings > Accounts > Family & other users, add a child account, and set up parental controls through the Microsoft Family Safety app. You can restrict browsing, set screen time limits, and block specific websites. This affects all browsers the child uses on that account.

On Mac, open System Preferences > Parental Controls, select the user account, and check "Disable private browsing." This prevents Safari and other browsers from opening private windows. On both systems, the restricted user cannot change these settings without the administrator password.

What happens when incognito is disabled

When you disable incognito mode, the private browsing option disappears from the browser menu. Users cannot open a new incognito window, and any attempt to do so (through keyboard shortcuts like Ctrl+Shift+N in Chrome) will fail silently or show an error message. All browsing history, cookies, and cached files are recorded and visible to anyone with access to the browser history.

Disabling incognito does not prevent users from clearing their history manually after browsing. If you need to monitor activity on a shared device, combine disabling incognito with parental controls that log all web activity, or use a network-level monitoring tool like a router with built-in parental controls.

Frequently Asked Questions

Can I disable incognito mode on just one user account?

Yes. Group Policy on Windows and parental controls on Mac both work at the user account level. A restricted account cannot use incognito, but an administrator account on the same device can. This is useful on family computers where you want to monitor children's browsing but not your own.

Will disabling incognito mode stop someone from hiding their browsing?

It will stop them from using the browser's built-in private mode, but it will not prevent them from clearing their history manually, using a different device, or using a VPN. If you need to monitor activity, combine disabling incognito with parental controls that log all web traffic, or use a network-level tool.

What if I disable incognito and then change my mind?

You can re-enable it by reversing the steps: in Group Policy, set the policy back to "Not configured," or in parental controls, uncheck the private browsing restriction. If you set a parental control passcode and forgot it, you will need to reset it through your account settings or contact your device manufacturer's support.

Does disabling incognito work on mobile devices?

Yes, but only through parental controls. On iPhone and iPad, use Screen Time to restrict Safari. On Android, use Google Family Link or your device's built-in parental controls. These methods prevent private browsing on all apps, not just the browser.

Can my employer disable incognito on my work computer?

Yes. Most employers use mobile device management or Group Policy to disable incognito, private browsing, and other privacy features on work devices. This is a standard security practice, and you should assume your work browsing is monitored regardless of whether incognito is disabled.
