How to prevent others from using your computer or tablet

The most basic security step is essential to keep others out: lock your computer or tablet with a strong password when not in use.

The lock screen suspends your activities and protects your work from potential snoopers without completely shutting down your computer. On Windows, you can use the shortcutWindows key + Lto lock down your PC quickly.

While you're at it, update your password to something more complex. It's easy to fall into the trap of setting a crude password on our home desktop or laptop, and I bet at least some of you lock your tablet with "1234" or something similar.

Unique and complex passwords take longer to create, but keep your information safe from prying eyes. Of course, you also need a great way to remind them.

Need help with the password?I bet you do. Here is a simple tutorial to create strong passwords.

And then there are the keyloggers

Keyloggers are programs that exist solely to capture information coming from your keyboard. They're a tool hackers can use to steal your information, but businesses, parents, and even entrepreneurial spouses can install them on their technology.

They come in the form of software and hardware and are not something to be taken lightly. Physical keyloggers are easy to hide inside computers, and you would never know it. They can also hang over wires and cables, and if you don't know what you're looking for, you can easily miss it. Fortunately, these external keyloggers are limited in what they can do.

How can you identify them? Hardware keyloggers come in many forms, including a USB stick, cable, or wall charger. Check your computer for anything that seems out of place or that you don't remember plugging in.

Unfortunately, the software counterparts are just as, if not harder, to spot. Also, they can do a lot more damage. Fortunately for you, you can use software to detect keyloggers on a Mac or PC.
