Lock computer screen on a Windows PC

There are several ways to lock your Windows computer. Here we discuss two convenient methods.

It is also an option to lock your screen from the Start menu. Click the Start button (the Windows flag) in the lower left corner of your screen. Then select your user account (usually at the top of the menu) and choose ‘Lock’.

This is slightly slower than the shortcut method, but is useful if you can’t find the Windows key or if your keyboard doesn’t have a Windows key.‍️

3. Set a password for extra security

Setting a password is a smart move for added security. This way you ensure that only you have access to your Windows PC. Whether you use a 27 inch monitor , the best 144hz monitor or a mini PC , follow these steps to set a password:

  1. Press the Windows key and select the gear icon (Settings).
  2. Click on ‘Accounts’ and then on ‘Sign-in options’.
  3. Under ‘Password’, choose ‘Add a password’.
  4. Enter a strong password, confirm it and add a hint if desired.
  5. Click ‘Next’ and then ‘Finish’.

Voila! Your Windows PC is now extra protected with a password. 🔐

Set up an automatic screen lock

Do you often forget to lock your screen? No problem! it is also an option to set an automatic screen lock. For example, your computer automatically locks after a certain amount of time of inactivity.

On a Windows PC, go to Settings > Accounts > Sign-in options and adjust the Pause screen after option . On a Mac, go to System Preferences > Desktop & Screen Saver > Screen Saver and adjust the Wait Time.

Handy if, for example, you have the best ultrawide monitor on which you do all your work and you want to quickly secure your screen.

Provide a strong and unique password

A strong password is essential for the security of your computer. Choose a combination of upper and lower case letters, numbers and symbols. Make it at least 6 characters long and avoid easily guessed words or phrases.

Also, use unique passwords for different accounts so that if one account gets hacked, the others stay safe. An option to achieve this without remembering it all is to use a good password manager.
