What Is Chrome Kiosk Mode? (And How to Set It Up)

Chrome kiosk mode locks your browser, or your entire Chromebook, to a single site or app with no way out for whoever is using it. It’s the same trick behind self-checkout screens, library catalog terminals, and the sign-in tablet at a doctor’s office. There are actually two different versions of it, and most guides mix them together. Here’s how each one works and which one fits what you’re trying to do.

What Chrome Kiosk Mode Actually Does

Turning on kiosk mode hides the address bar, tabs, bookmarks bar, and every other piece of the normal browser. Whoever sits down at the device only sees the one website or app you chose. They can’t open a new tab, type a different URL, or back out to the desktop.

Two Different Kinds of Kiosk Mode

This is the part most articles get muddled. There are two separate features that share the same name.

• Browser kiosk mode. A launch flag that opens Chrome full screen, locked to one URL. Works on any computer, Windows, Mac, Linux, or a Chromebook. Takes two minutes to set up and just as fast to undo.
• ChromeOS Single-App Kiosk Mode. A true device-level lockdown built into ChromeOS itself. The Chromebook boots straight into one app or site with no sign-in screen, no Shelf, and no way to reach the rest of the system. This is what schools, libraries, and stores actually use for unattended devices.

Method 1: Quick Browser Kiosk Mode (Any Computer)

Use this when you just need a temporary, simple lockdown, like a laptop at a trade show booth or a demo station.

1. Right-click your Chrome shortcut and select Properties (Windows) or duplicate the app and rename it (Mac).
2. Find the Target field.
3. Add a space at the end, then type –kiosk https://yourwebsite.com, replacing the URL with the one you want locked in.
4. Click Apply, then OK.
5. Double-click the shortcut. Chrome opens full screen with no visible browser controls, locked to that one page.

This method only controls the browser, not the device itself. Someone could still use a keyboard shortcut to minimize the window or reach other apps unless you also lock down the operating system separately.

Method 2: True Single-App Kiosk Mode on a Chromebook

This is the real deal, an actual device lockdown rather than just a browser trick. How you set it up depends on whether your Chromebook is managed by a school or business.

If Your Chromebook Is Managed (School or Work)

You’ll need a Chrome Enterprise, Chrome Education, or Kiosk & Signage management license tied to the device, and an administrator account. If that’s you, the setup happens in the Google Admin console:

1. Go to Devices > Chrome > Apps & extensions > Kiosks.
2. Click the + icon and add an app from the Chrome Web Store, or add a web URL directly.
3. Set it as the Auto-launch app so the device boots straight into it.
4. Push the policy to the relevant organizational unit.

If you’re not the administrator, ask whoever manages your school or company’s Chromebooks to make this change. Regular users can’t access the Admin console.

If Your Chromebook Is Personal and Unmanaged

Google built a manual option for this, but there’s a catch. It only works on Chromebooks made before 2017. Newer models require a management license, even for a personal device, so check your Chromebook’s release year before trying this.

1. Sign in to your Chromebook.
2. Open Chrome and type chrome://extensions in the address bar.
3. Turn on the Developer mode toggle in the top right of that page. This only affects the Extensions page itself. It is not the same as ChromeOS Developer Mode, and it does not weaken your Chromebook’s security.
4. Click Manage kiosk applications.
5. Enter the App ID of a kiosk-supported Chrome Web Store app, or the web address you want locked in.
6. Click Add, then Done.

Who Actually Needs This

• Front desks and check-in stations. Visitors fill out one form with no way to wander into anything else.
• Digital signage. A single web page or slideshow that loops endlessly with nothing to click.
• Classroom testing. Students see only the test app, with no way to open another tab and search for answers.
• Retail and self-checkout. One ordering or checkout app, nothing else reachable.
• Library and lobby terminals. A catalog search tool or directory, locked so the public can’t browse the open web.

How to Exit Kiosk Mode

The way out depends on which method you used.

• Browser kiosk mode: Open the Task Manager (Windows) or Activity Monitor (Mac) and quit Chrome from there, since there’s no visible window control to click.
• ChromeOS Single-App Kiosk Mode: Press Ctrl + Alt + S on the kiosk screen to sign out, or hold the power button to restart the device back into kiosk mode at the next boot.

Good to Know

• Chrome apps in kiosk mode are gradually being phased out in favor of Progressive Web Apps (PWAs) and Android apps. If you’re choosing what to deploy for the long term, a PWA is the safer bet.
• Browser kiosk mode does not support Chrome extensions, so any tool you rely on needs to be built into the website itself.
• You can block or allow up to 1,000 specific URLs inside a managed kiosk, useful if your kiosk app needs to reach a few outside resources, like a payment processor.

Frequently Asked Questions

Does kiosk mode work on a regular Windows laptop?
Yes, the browser kiosk flag works on any device that runs Chrome. Single-App Kiosk Mode is ChromeOS only.

Can someone get out of kiosk mode by pressing keyboard shortcuts?
Browser kiosk mode can sometimes be exited with Alt+F4 or similar shortcuts unless you also restrict the operating system. ChromeOS Single-App Kiosk Mode is much harder to escape since it controls the whole device, not just Chrome.

Do I need to pay for this?
The browser kiosk flag is free on any device. True ChromeOS Single-App Kiosk Mode on devices from 2017 onward requires a paid Chrome Enterprise, Education, or Kiosk & Signage license.

Will turning on Developer mode in chrome://extensions hurt my security?
No. That toggle only affects what you can do on the Extensions page, like loading unpacked extensions and managing kiosk apps. It is unrelated to the system-level ChromeOS Developer Mode that disables Verified Boot.

Browser kiosk mode is a two-minute fix for a temporary, single-purpose screen. ChromeOS Single-App Kiosk Mode is the real lockdown built for devices that run unattended day after day. Pick the one that matches how permanent your setup needs to be.
