Locking a browser can prevent others from viewing your bookmarks, browsing history, saved passwords, etc. However, popular browsers like Chrome, Safari, Edge, Firefox, Brave, and Opera do not provide a built-in option to lock the entire browser.
On a computer, you can use a browser lock app or extension to password-protect your browser. On a phone, you can also use the device’s built-in feature. This guide shows you easy ways to lock browsers with password.

Method 1: Use Cisdem AppCrypt

With AppCrypt, you can:

Follow the steps below to lock browsers with AppCrypt on Windows or Mac:
1. Download this browser lock app and install it.
Free Download Windows 11/10/8/7 
Free Download macOS 10.15 or later
2. Set a password when you first launch it.
3. Click the lock icon on your Windows task bar/Mac menu bar. Choose Open Main Window.
4. Enter the password to access the main window.
5. Click App Lock in the upper left corner. Click the Plus icon. Select the browser app you want to lock. Click Open.
(Note: On a Mac, find the browser app from the Applications folder and click Open.
On Windows, directly drag and drop the app’s shortcut icon into the program. If you’re unsure how, check this tip.)
Now the browsers are locked with password on your computer.
Tip 1: How to make the browser lock app more effective?
After adding browsers to the App Lock list, go to Preferences and enable Launch at system startup. This allows AppCrypt to start automatically whenever your computer starts, keeping the selected browsers protected.
You can also set the auto-lock time in the App Lock section. If an locked browser remains inactive for a period of time, AppCrypt will automatically lock it again.
Tip 2: How to find the browser app’s shortcut icon?
You can lock a browser by dragging and dropping its desktop shortcut into the program.
If their is no desktop shortcut, search for the app in the Start menu. Right-click it and select “Open file location”. A File Explorer window will appear, showing the app’s shortcut file. Just drag it to the App Lock tab.
Method 2: Use Browser Lock extension
A browser lock extension is a simple way to set password for your browser. It is easy to install and does not require an additional app. However, it provides only basic protection and has some limitations, such as being easy to bypass, only locking specific browsers, and possibly not working in Incognito mode.
Browser Lock by browserlock.io is a free extension that supports Chrome, Edge, and Opera. With this extension, you can:
- Lock your browser Chrome, Opera, and Edge with a password for free.
- Set up password protection in just a few clicks.
- Quickly lock your browser using the right-click menu or keyboard shortcuts.

For example, on a Windows PC, you can open File Explorer and go to: C:\Users\Administrator\AppData\Local\Google\Chrome\User Data\Default\Extensions. Then you'll see the extension files on Chrome. Simply select them and press the Delete key. The extension will be removed from Chrome and the browser lock will no longer work.

Locking a browser on a phone is also very simple. You can use a third-party app locker to set password for your browser. Or use the built-in app lock feature on your phone.
Method 1: Use Cisdem AppCrypt
Cisdem AppCrypt is also available for Android and iPhone. It lets you lock Chrome, Safari, Firefox, and other browser apps to prevent unauthorized access. Since the steps differ slightly between Android and iPhone, I’ll show you how to do it on each device separately.
Steps on Android

Most phones include a built-in app lock feature that lets you lock apps with a passcode, fingerprint, or Face ID. You can use the feature to lock your browser too.
