If you are using a Microsoft account, all devices you have ever logged in with are added to your Microsoft account device settings.
You can then manage a device through these online settings. This also allows you to lock the computer remotely. Locking a remote PC helps you secure your PC.
Suppose you ever forget to lock your PC. In that case, you can still lock the PC by first logging in to your Microsoft account through the browser. After you log in, find the computer you are trying to lock. Then, you can enter a message to the active user before you remotely lock the PC.
