Why we should keep changing our password on regular interval of time?


In this 21st century, the internet is a boom to us, where our every problem is solved at ease and in very less time. But there are people who use the Internet for taking advantage of others and doing frauds just for their fun sake and earn some money. These types of people are known as ‘Black Hat Hackers’.

‘Hacker’ is the term given to those, who can access your data with or without the owner’s permission. Neither it is a good term nor a bad one but just Hacker. People who use their knowledge for good purpose are known as ‘White Hat Hacker’ whereas people who use the same for wrong work are known as ‘Black Hat Hacker’. The whole act, which is done by the hacker, is known as ‘Hacking’.

At one point or another, every single person might have faced some phone calls, e-mails or SMS, from strangers claiming themselves as genuine and legitimate employees of the bank. They start earning your trust and later they ask for your personal information such as your bank account number, credit/debit card number, CVV, etc. They will use this gathered information for their advantage. Which is known as ‘Social Engineering’.

Likewise, there are some web sites, web applications or mobile applications, which will ask you for password or there may be a case, when you download something from the internet, they will prompt you with a form asking you to register for downloading or some web sites claim to give you more discount or redeem coupons as compared to others, just by signing or logging into them.
