We use a password to log in into everything these days, from your mobile apps to your house doors. But using password really makes the content that secure? The short answer is no. There are many cases where your account is hacked and your password is revealed. To get hold of this problem, the modern world has a new way for you to log in into your account, that is two factor authentication. As the title suggests, this lets you access your account with two passwords. Mostly, one of them is your regular password, and the other is a random password that is sent to your mobile device at the time of login. Also, the random password expires after certain period of time, usually 1 minute. This makes the hacker or any person who wants to get into your account really had to get into it. Tech giants these days has been implementing this feature in their websites or their apps like Amazon, Facebook, etc.
