You can disable incognito mode through your browser settings, but the method differs by browser and your operating system

If you want to prevent incognito browsing on a device — whether you're a parent managing a child's computer or an administrator controlling workplace machines — you have options. Most browsers let you turn off incognito through settings, though some require operating system-level controls or additional tools. The steps depend on which browser you use and whether you're on Windows, Mac, or a Chromebook.

Disabling incognito is not the same as clearing browsing history. Incognito mode (called "Private Browsing" in Firefox and Safari) leaves no local record of sites visited, cookies, or searches. Turning it off prevents users from opening new incognito windows or tabs at all.

Key Takeaways

  • Chrome and Edge let you disable incognito through Settings > Sync and Google Services (Chrome) or Settings > Privacy (Edge), but only if you're signed in as the device owner.
  • Firefox and Safari do not have built-in settings to disable private browsing, so you must use parental controls or device-level restrictions instead.
  • On Windows, you can use Group Policy Editor to block incognito across all browsers if you have administrator access.
  • On Mac and Chromebook, parental controls through Screen Time or Family Link are the most direct route to prevent private browsing.
  • Disabling incognito at the browser level is easier to bypass than device-level restrictions, so choose based on how determined the user is to circumvent it.

Disabling incognito in Chrome

In Chrome, you can turn off incognito mode through your account settings if you are the device owner or have administrator privileges. Open Chrome, click the three-dot menu in the top right, select Settings, then go to Sync and Google Services in the left sidebar. Scroll down to find Sync everything or Manage sync and look for an option labeled Allow Incognito or similar. Uncheck this box.

This method only works if you are signed into Chrome with a Google account that owns the device. If the person using the browser is signed in with a different account, they may still be able to open incognito windows. For stronger control, use Chrome Enterprise policies if your device is managed by a workplace, or set up Google Family Link if you are managing a child's account.

Disabling incognito in Edge

Microsoft Edge has a similar setting to Chrome. Open Edge, click the three-dot menu, go to Settings, then select Privacy, search, and services from the left menu. Scroll down to Clear browsing data and look for Allow InPrivate browsing (Edge's term for incognito). Toggle this off.

Like Chrome, this works only if you are signed in as the device owner. If you need to block it for other users on the same computer, you will need to use Windows Group Policy or parental controls instead.

Firefox and Safari: using parental controls instead

Firefox and Safari do not have built-in settings to disable private browsing mode. Instead, you must use your operating system's parental controls or device restrictions.

On Mac, open System Settings (or System Preferences on older versions), go to Screen Time, and select the user account you want to restrict. Under Content & Privacy, enable restrictions and navigate to Websites. You can limit access to adult sites, but this does not directly block private browsing. A more effective approach is to use Parental Controls (available in some Mac versions) or third-party tools like Net Nanny or Bark, which can monitor and block private browsing across all browsers.

On Windows, use Parental Controls through Settings > Accounts > Family & other users, or use Group Policy Editor (see the Windows section below) to block incognito across all browsers at once.

Using Windows Group Policy to block incognito across all browsers

If you have administrator access on a Windows computer, you can disable incognito mode system-wide using Group Policy Editor. This blocks private browsing in Chrome, Edge, and most other browsers on that machine.

Press Windows key + R, type gpedit.msc, and press Enter. Navigate to Computer Configuration > Administrative Templates > Google > Google Chrome (or the equivalent folder for Edge). Look for a policy called Incognito mode availability or InPrivate browsing. Double-click it and set it to Disabled. Click Apply and OK.

This method requires administrator rights and works only on Windows Pro, Enterprise, or Education editions. Home edition does not include Group Policy Editor. If you are on Home edition, use parental controls or a third-party monitoring tool instead.

Using Google Family Link for child accounts

If you are managing a child's Google account, Google Family Link is the most straightforward way to control incognito access across their devices. Set up Family Link through families.google.com, add your child's account, and go to their device settings. Under Controls on Google Play or App restrictions, you can limit access to certain apps and features, including private browsing in Chrome.

Family Link also lets you see which sites your child visits (if you enable Web & App Activity), set screen time limits, and manage app downloads. It works on Android, Chromebook, and some Windows devices linked to a Google account.

Using Chromebook parental controls

On a Chromebook, you can disable incognito mode through the device owner's account settings. Sign in as the owner, open Settings, go to Users and accounts, and select the supervised user account. Under Parental controls, toggle off Allow Incognito mode or Allow guest browsing.

Chromebooks managed by a school or workplace may have additional restrictions set by the administrator. If the device is managed, you will not see these options — the administrator controls them remotely.

Why disabling incognito matters and what it does not do

Disabling incognito prevents users from opening new private browsing windows, which stops the browser from automatically deleting cookies, cache, and browsing history at the end of the session. This means activity becomes visible in browser history and may be logged by network monitoring tools.

However, disabling incognito does not prevent someone from using a different browser, accessing the internet through a mobile hotspot, or using a VPN to hide their activity. It is a friction point, not a complete barrier. If you are trying to monitor a child's online activity, combine it with parental controls that cover multiple browsers and devices, and have open conversations about online safety.

Frequently Asked Questions

Can I disable incognito on just one user account on my computer?

Yes, on Windows through parental controls or Group Policy (if you have administrator access). On Mac, use Screen Time for the specific user account. On Chromebook, disable it through the owner account's parental controls for that supervised user. Browser-level settings in Chrome and Edge apply to whoever is signed in, so if multiple people use different accounts, you can restrict each one separately.

What if someone just opens a different browser to get around the incognito block?

Browser-level restrictions only affect that browser. To block private browsing across all browsers, use operating system controls: Group Policy on Windows, Screen Time on Mac, or Family Link on Chromebook. Third-party monitoring tools like Bark or Net Nanny can also enforce restrictions across multiple browsers.

Does disabling incognito mode prevent someone from hiding their activity?

It prevents them from using that specific browser feature, but not from using a VPN, a different device, or a different browser entirely. Disabling incognito is most effective when combined with network-level monitoring (through your router or a tool like Firewalla) and open communication about expectations.

Can I re-enable incognito mode after I disable it?

Yes. Follow the same steps you used to disable it and toggle the setting back on. If you used Group Policy, open gpedit.msc again, find the same policy, and set it to Not configured or Enabled.

Does disabling incognito affect my own browsing on the same device?

If you disable it through your own account settings in Chrome or Edge, it affects only your account. If you disable it through Group Policy or parental controls, it affects all users on that device. Check which method you used before disabling it.
