You can disable Chrome's Incognito mode through Settings, but the method depends on whether you're managing your own device or a work computer

If you own the computer, you disable Incognito by changing a Chrome setting in about 30 seconds. If your computer is managed by an employer or school, Incognito is likely already blocked by a policy you cannot override yourself — you would need to contact your IT department.

The reason to disable Incognito is usually parental control: you want to prevent someone else from browsing without a history record. On a shared device, turning off Incognito closes that loophole. On a work device, your organization blocks it to keep activity auditable.

Key Takeaways

  • On your own device, go to Chrome Settings, then Policies, then Incognito mode, and select "Disallow incognito mode".
  • Once disabled, the Incognito option disappears from the menu — users cannot turn it back on without changing the setting again.
  • If you see no Incognito option in Settings, your device is already managed by an organization and you cannot change this setting yourself.
  • Disabling Incognito does not delete existing browsing history or affect regular (non-Incognito) browsing.

How to disable Incognito on your own Windows or Mac computer

Open Chrome and click the three vertical dots in the top right corner. Select Settings. On the left sidebar, click You and Google, then scroll down and click Manage your Google Account. Click the Security tab at the top.

Scroll down to the section labeled Your devices and click Manage all devices. Find your current device in the list and click it. Scroll down to Chrome browser settings and look for Incognito mode. Click the dropdown menu next to it and select Disallow incognito mode. Chrome will explore this change when ready — the Incognito option will no longer appear when you click the menu button.

If you do not see a Manage your Google Account option, or if the Security tab does not show device settings, your version of Chrome may be older. Update Chrome by clicking the three dots, selecting Help, then About Google Chrome. Chrome will check for updates and install them automatically.

What happens after you disable Incognito mode

Once disabled, Incognito disappears from the Chrome menu entirely. When someone clicks the three-dot menu, they will not see the "New Incognito window" option. They cannot open an Incognito window using the keyboard shortcut (Ctrl+Shift+N on Windows, Cmd+Shift+N on Mac) — Chrome will show an error message instead.

Disabling Incognito does not affect regular browsing. History, bookmarks, and extensions all work normally. If someone was already using Incognito before you disabled it, their Incognito windows will close, but their regular browsing history remains untouched.

If your device is managed by an organization

Work computers, school computers, and some family-managed devices use Chrome policies set by an administrator. These policies override individual user settings. If Incognito is disabled by policy, you will not see the option to change it in Settings — the setting straightforward will not appear.

If you need to use Incognito on a managed device, contact your IT department or system administrator. They control whether the policy can be changed. On a school device, this is usually not possible. On a work device, it depends on your organization's security rules.

Why you might want to disable Incognito

Parents often disable Incognito on shared family computers to prevent children from browsing without a history record. Incognito mode leaves no trace on the device — no cookies, no cached files, no browsing history — which makes it useful for privacy but also makes it a way to hide activity.

Employers and schools disable Incognito to maintain audit trails. If a device is used for work or school, the organization may require that all browsing be logged. Disabling Incognito ensures that requirement is enforced.

Re-enabling Incognito if you change your mind

To turn Incognito back on, follow the same path: Settings > You and Google > Manage your Google Account > Security > Manage all devices > Your device > Chrome browser settings > Incognito mode. This time, select Allow incognito mode from the dropdown. The Incognito option will reappear in the Chrome menu within seconds.

If you forgot where you disabled it or cannot find the setting, you can also reset Chrome to its default state. Click the three dots, go to Settings, scroll to the bottom, and click Reset settings. This will turn Incognito back on, but it will also reset other Chrome settings like your homepage and search engine.

Frequently Asked Questions

Can someone turn Incognito back on if I disable it?

Only if they have access to the same Google Account and know the Settings path. If you are the only one with the password, they cannot change it. On a managed device, they cannot change it at all — only the administrator can.

Does disabling Incognito delete old Incognito browsing?

No. Disabling Incognito only prevents new Incognito windows from opening. It does not affect any browsing that already happened. Incognito windows that were already open will close, but no history is created or deleted.

What if someone uses a different browser to avoid the Incognito block?

Disabling Incognito in Chrome only affects Chrome. Firefox, Safari, Edge, and other browsers have their own private browsing modes that work independently. If you need to block private browsing across all browsers, you would need to use parental control software or device-level restrictions, not just Chrome settings.

Will disabling Incognito slow down Chrome?

No. Disabling Incognito has no effect on Chrome's speed or performance. It only removes the option from the menu.
