You can disable incognito browsing through your browser settings, your device's parental controls, or your network — the method depends on who you're trying to restrict and what device they're using.

Incognito mode (called Private Browsing in Safari and Firefox) leaves no history, cookies, or cached files on the device. If you're a parent wanting to prevent a child from using it, or an employer managing company devices, you have several routes. Each one works differently and blocks incognito in different ways — some stop it entirely, others just make it harder to access without blocking it completely.

The easiest method is usually your browser's built-in settings. If you need to restrict it across all browsers or on a shared device, you'll move to your operating system's parental controls or device management tools. Network-level blocking (through your router or workplace network) is the hardest to bypass but requires technical setup.

Key Takeaways

  • Chrome, Edge, and Firefox all have settings to disable incognito mode, found in their preferences or policies — this is the fastest method for a single browser.
  • Windows and Mac parental controls can block incognito across all browsers at once, but require you to set up a separate account for the person you're restricting.
  • Chromebooks use Google Admin Console or Family Link to disable incognito, and this setting syncs across all devices the user signs into.
  • Network-level blocking through your router or workplace firewall stops incognito mode from working even if someone changes browser settings, but requires access to your network equipment.
  • A determined user can still bypass browser-level blocks by using a different browser, a private VPN, or a device you don't control — no single method is completely foolproof.

Disabling incognito in Chrome and Edge

Chrome and Edge use the same underlying engine, so the process is nearly identical. Open Chrome or Edge, go to Settings (the three-dot menu in the top right), then select Settings again from the dropdown. On the left sidebar, click You and Google (Chrome) or Profiles (Edge), then Manage other people.

Find the profile you want to restrict and click the three-dot menu next to it. Select Edit, then check the box that says Block this person from using Guest mode (Chrome) or Restrict this profile (Edge). This doesn't directly disable incognito, but it prevents someone from switching to a guest profile where incognito is always available. To fully block incognito in the main profile, you'll need to use your operating system's parental controls instead — browser settings alone won't stop it.

If you're managing a work device or school Chromebook, your organization may have already set a policy that disables incognito across all Chrome browsers. You can check whether a policy is active by typing chrome://policy into the address bar and looking for "IncognitoModeAvailability" in the list. If it shows "Disabled", incognito is already blocked by your administrator.

Disabling incognito in Firefox and Safari

Firefox doesn't have a built-in setting to disable private browsing mode directly. Instead, you'll need to use your device's parental controls (Windows Parental Controls or macOS Screen Time) to block it system-wide, or use a Firefox extension like LeechBlock NG or News Feed Eradicator that can restrict certain browser features — though these are workarounds, not official blocks.

Safari on Mac and iPhone also lacks a direct incognito-disable setting. On Mac, use Screen Time (System Preferences > Screen Time) to restrict private browsing. On iPhone or iPad, open Settings, tap Screen Time, then Content & Privacy Restrictions, and toggle off Private Browsing. This removes the Private Browsing option from Safari entirely on that device.

Using Windows Parental Controls to block incognito across all browsers

Windows 10 and 11 parental controls can disable incognito mode system-wide, but only for a child account — you must set up a separate user profile for the person you're restricting. Open Settings, go to Accounts, and click Family & other users. Click Add a family member and create a child account (not an adult account). The child account must be a Microsoft account, not a local account.

Once the child account is created, sign out and sign into that account. Open Microsoft Edge, go to Settings > Privacy, search, and services, and scroll down to Clear browsing data. Toggle on Choose what to clear every time you close the browser. Then sign back into your admin account, open Settings > Accounts > Family & other users, click the child account, and select Manage family settings online. In the Microsoft Family Safety dashboard, go to App and game restrictions and set restrictions as needed — though Windows doesn't have a direct "disable incognito" toggle, restricting browser extensions and enforcing Safe Search limits what the child can do in private mode.

A more direct approach: use Group Policy Editor if you're on Windows Pro, Enterprise, or Education edition. Press Windows key + R, type gpedit.msc, and press Enter. Navigate to Computer Configuration > Administrative Templates > Google > Google Chrome > Incognito Mode. Double-click Incognito Mode Availability and set it to Disabled. This blocks incognito in Chrome only, not other browsers.

Using macOS Screen Time to block incognito

On Mac, Screen Time is the system-wide parental control tool. Open System Preferences (or System Settings on Monterey and later), click Screen Time, then Options in the bottom left. If you're setting restrictions for another user, click Family instead and select the family member you want to restrict.

Click Content & Privacy, then Web Content. Choose Limit Adult Websites or Custom (if you want to block specific sites). Then go back and click Apps. Find Safari or Chrome in the list and toggle it off, or set time limits on it. To specifically block private browsing in Safari, go to Content & Privacy > Restrictions and look for a Private Browsing toggle — if it appears, turn it off. Note that this method works best if the restricted user doesn't have admin access to the Mac.

Blocking incognito on Chromebooks and with Google Family Link

Chromebooks managed by a school or workplace use Google Admin Console, where an administrator can disable incognito for all users on the device. If you're a parent managing a child's personal Chromebook, use Google Family Link. Open the Family Link app on your phone or go to families.google.com on a computer. Select your child's account, tap Controls on Google Play, then App settings. Look for Incognito Mode or Private Browsing and toggle it off if the option appears.

If Family Link doesn't show an incognito toggle, you can restrict it through the child's Chromebook directly. Sign into the Chromebook with your parent account, open Settings, click Manage other people, select your child's account, and check Restrict this user. Then sign back in as your child and try to open incognito — it should be blocked or require a parent PIN to access.

Blocking incognito at the network level

If you want to block incognito mode on all devices connected to your home or office network, you can configure your router or use a DNS-level filtering service. This is the hardest method to bypass because it works regardless of browser or device settings.

Most home routers don't have a direct "disable incognito" setting, but you can use a service like OpenDNS, Cloudflare for Families, or NextDNS to filter traffic at the DNS level. These services intercept requests before they reach your browser and can block certain types of traffic. Set your router's DNS servers to point to one of these services, then configure the filtering rules in their dashboard. This approach requires some technical knowledge and won't completely stop incognito mode — a user can change their device's DNS settings or use a VPN to bypass it.

In a workplace, your IT department can use a proxy server or firewall to monitor and restrict incognito mode. This is more reliable than home network blocking because the organization controls the network infrastructure and can enforce policies across all devices.

Why someone might bypass your block and what you can do about it

Browser-level blocks are the easiest to work around. A user can switch to a different browser you haven't restricted, use a private VPN, or access the internet from a different device. If you're trying to restrict a child's browsing, the goal isn't usually to make it impossible — it's to make it inconvenient enough that they think twice, and to have a conversation about why you're setting the boundary.

If you discover someone has bypassed your settings, check what method they used. Did they switch browsers? You may need to restrict multiple browsers or use parental controls instead. Did they use a VPN? Some parental control apps can detect VPN use and alert you. Did they use a different device? You'll need to extend your restrictions to that device too. The most effective approach combines browser settings, device-level controls, and open communication about why the restrictions exist.

Frequently Asked Questions

Can I disable incognito mode without creating a separate user account?

On Windows and Mac, parental controls require a separate account for the person you're restricting. If you want to disable incognito on your own account without creating a new user, use Group Policy Editor (Windows Pro/Enterprise) or edit your browser's policy files directly. On Chromebooks, you can restrict incognito through Family Link without a separate account if you're the parent.

Will disabling incognito mode stop someone from hiding their browsing history?

No. Incognito mode is one way to hide history, but someone can also manually clear their browser history, use a VPN, or use a different device. Disabling incognito removes one option, but it's not a complete solution. If you're concerned about what someone is browsing, consider having a direct conversation or using monitoring software designed for that purpose.

What happens if someone tries to open incognito when it's disabled?

In Chrome and Edge, the incognito option straightforward won't appear in the menu. In Safari on iPhone, the Private Browsing toggle is removed from settings. If someone tries to use a keyboard shortcut (like Ctrl+Shift+N in Chrome), nothing happens — the window doesn't open. On Chromebooks with Family Link, trying to open incognito may prompt a request for parental approval.

Can my workplace block incognito mode on my personal device?

Only if you're using a company-provided device or signed into a work account that has device management enabled. If you're using your own personal device and your own browser account, your employer cannot disable incognito mode unless you've explicitly enrolled that device in their management system. Check your device settings or ask your IT department if you're unsure whether your device is managed.

Does disabling incognito mode affect regular browsing speed or performance?

No. Disabling incognito mode has no effect on how fast your browser runs or how much memory it uses. It only removes the option to open a private browsing window. Your regular browsing experience stays exactly the same.
