How To Keyboard Lock On Mac

If you have ever needed to temporarily prevent keyboard input on your Mac, there is a simple solution you might not be aware of – it’s called keyboard locking. In this blog post, we will walk you through the steps on how to keyboard lock on Mac.

Method 1: Use macOS Built-In Functionality

In order to lock your keyboard on a Mac, you can use a built-in functionality of macOS known as “Fast User Switching”. This allows you to quickly switch to a login screen without closing any running applications.

  1. Go to System Preferences.
  2. Choose Users & Groups.
  3. Click on Login Options.
  4. Check the box next to Show fast user switching menu as.

Once you have activated the fast user switching, you can lock your keyboard by selecting Login Window from the user switching menu at the top right of the screen. This will take you to the login screen, locking your keyboard until you enter your password.

Method 2: Use Third-Party Applications

If you are looking for a more immediate way to lock your keyboard, you might want to consider using third-party applications such as Keyboard Cleaner or Lockey.

Here is an example of how you can use Keyboard Cleaner:

1. Download and install Keyboard Cleaner.
2. To lock your keyboard, simply open the application.
3. To unlock your keyboard, simply quit the application (usually by pressing Command-Q).

The process is similar with Lockey, except that you can customize a shortcut for locking and unlocking your keyboard.


In this blog post, we have explained two methods on how to lock your keyboard on a Mac. While there is no direct keyboard lock function in macOS, you can use the built-in fast user switching feature or third-party applications to achieve this. Remember, it is always crucial to keep your work secure, especially if you have to step away from your computer for a few moments.
