What is a Windows Security button? All you need to know

Balancing security and accessibility can be a tough ask. Users don’t look kindly upon manufacturers and developers that trade one for the other. These two components have become a priority for PC users. One area where we see the two combine to offer the best of possibilities is the Windows Security button.

Nowadays, more and more developers are adding a physical security button to their devices to give users more security without sacrificing ease of access and functionality.

But what is the Windows Security button exactly, where can you find it on your tablets and PCs, and how do you use it? All this and more coming up!

What is the Windows Security button?

As the name suggests, the Windows Security button is a security feature that lets you safely access the login menu and sign in to your device with your password. 

Smartphones are definitely ahead of the game in this case. But Windows portable devices, such as tablets, have begun adding a Windows security button that serves more than just a way to keep out unwanted users. It also offers additional login menu options.

Although if you’re trying to find a Windows Security button on your desktop PC or laptop, you may be disappointed. Why is that?

Tablets vs PCs

The Windows Security button is a physical button that is present on devices such as tablets. These portable devices can also be used without a keyboard but it isn’t possible to use a keyboard without unlocking the device. This makes it harder to login in different scenarios, which is why having a dedicated physical security button makes much more sense.  

On PCs, however, no such limitations exist, and thus, there’s no need to have a Windows security button. Although, the same Windows security login screen can be accessed by pressing the hotkey combination Ctrl + Alt + Del

This functions in the same way as the Windows security button, allowing you to access the login menu options with ease. 

On PCs, pressing this combination triggers the Secure Attention Sequence (SAS), a hardware-generated non-maskable interrupt. That means, if the hotkeys are pressed, the user has to go through the screen and enter the appropriate login information to get in. On tablets, because the on-screen keyboard is software-based, the SAS function cannot be generated, which is the main purpose of having the Windows Security button on them.

This does provide a layer of security to your device data so that, if enabled, no one can get access to your device without entering the username and password first.

Where is the Windows Security button?

Depending on your tablet’s manufacturer the Windows Security button may be placed in a different location than the rest. 

However, in most cases, you can find it somewhere along the sides, the bottom, or the top of the device. If you’ve ever used a smartphone before, you know what you’re looking for. 

An important note to make here is that not all Windows tablets will have a Windows Security button. Whether or not your Windows tablet has the security button or what its particular functionalities include is all up to the manufacturer. 

How to use the Windows Security button

When your device has been out of use for some time or when it is booting up, the Windows Security button can be pressed to access the login menu options. You can then proceed with entering your username and password as you would on any other Windows device. 

As mentioned, this is not unlike other portable devices where there is a dedicated hard key for certain functions like waking up the device and logging in using biometrics or a password. 

When do you need to enable the Windows Security button?

If your tablet has a dedicated Windows Security button, in most cases it would already be enabled by default. But if there is no such button on your device, the Ctrl + Alt + Delete hotkey combination can be enabled in its stead if it already isn’t so.
