Privacy is a term most people take lightly, especially on their devices and the internet. In fact, given the times we live in, one should think long and hard. Our devices contain more vulnerable information than our house lockers do. Moreover, people in high official positions are also vulnerable to online hackers as their devices contain priceless data about their companies. If these devices fall into the wrong hands, it can cost people their livelihood and, in worst-case scenarios, all their employees.

But let’s come down to the first wall of security for our computers. At times, we have to reluctantly share our macs with our spouses, children, siblings, friends and colleagues. And we all have some personal files containing our journals, bank details, passwords, personal data that we do not want anyone to know about. So when we have to share our macs with someone or leave it open to pick up an urgent call, chances are people will try to investigate each folder because of “no boundaries!”.

Not only does it trigger us and hurts us, but it might also be extremely embarrassing. It is in these moments that we want to punch that person hard who is probably laughing their heads off by now. But then again, what’s the point, right? You cannot undo it but ensure it does not happen to you again. Setting a password is the best way to keep all your files and folders safe from prying eyes. Here’s how you can do it.
