What is Two-Factor Authentication? Why is it urgent? - More Details here

As long as it is going, people are becoming more dependent online more slowly. Today, our livelihood, bank accounts, e-commerce site accounts (shopping) etc. have become dependent on everything, and security is becoming a very important matter in this case. What do you do to keep your online accounts safe? -Will keep the long and difficult password in the accounts? And this password is only in your brain? Believe it or not, your account password may be hacked. To make your accounts truly secure, the two-factor authentication system, which is a type of lock, whose code changes frequently. So far, I have written a lot of posts about cyber security, in almost every post I've mentioned this term. In this article you will know everything ...

Why not just password?

We use the password to access almost all of the accounts we have online. In an account we entered the username and password, we got access to that account. This method is called One-Factor Authentication, since you only need one thing to access that system. Today, as online services are increasing, along with the online accounts will also increase, it is normal. But remembering different passwords in different accounts is really a lot of hard work to do. Many people use one password in their account, but many people choose a simple password to remember (using their own name, parent's name), which are a lot easier to guess. Moreover, if you have access to an online account using cyber cafe or college public computers, the chance of getting your account hacked greatly increased.
Hackers may install malware on your computer, so you can steal all your password hackers. Apart from installing keylogger, what you are typing on the computer, everything can go to the hacker. So your password is as strong and lengthy as it can be able to handle the hacker comfortably, even you can not understand, your password is stolen. In addition to hacking your WiFi network, you can access the password to the hacker before reaching your password on that site, as it is a man-in-the-middle attack It is said.
Besides, by using a brave force attack someone will guess your password repeatedly, and if you get the right password, your account will be able to login easily. That's why bank account services are not just working with passwords, they require answers to your security questions or need to share your birth date or separate secret details. But even then one-factor authentication or just username and password is not a safe security system.

Two-factor authentication

If you are asked to keep any money chest securely, but what do you do? Of course not only depends on the lock of the ark, do not you? You may place the ark in a protected room and lock it in the room too, with a security guard placed outside the room, with a view to guard. If a person needs to take money from that chest, he must first introduce himself to the security guard, then he must have a key to that room, and at the end only he can reach the money only if the chest is in the key. Such multilevel security systems in the online world are called Multi-Factor Authentication (MFA), and are also called Two-Step Verification and - to access the computer system, you have to cross many security steps. .
But most of today's security systems ensure security in two stages, giving the user access to that system. First of all you need to enter your username and password and in the second step, you need to enter a special password that can be changed frequently. Because there are two steps to accessing the system here, it is called Two-Factor Authentication.

One-time password

So once we have entered the username and password then what is the special password to enter? The second password is a temporal password, which is only valid for some time and gets lost once it is used, and then need to generate a new password. And each time the variable password is called a one-time password (OTP). This Temporary password is a combination of a few numbers or series, which does not have any meaning. This is a serial number generated by a computer, which is sent to you on an electronic system by a user name and password after logging in.
Most of the time, this is the OTP that is sent to your cellphone number, which you can access on that system by entering. There are currently apps for generating OTPs, which are installed on your mobile, and it generates random numbers automatically, which you can use to login your account. Again, the two-factor authentication was completed through security keys, USB etc.

Use Two-Factor Authentication

Previously the websites provided full access to the user name and password only. But now banking websites, mail sites, Google, Yahoo, PayPal, Apple etc provide two-factor authentication services for security purposes. It has something to keep in mind about you, such as your password and you have something physically available, like another code, which is sent to you via SMS. There is currently an app named Google Authenticator, where the OTP syncs the server and the app at the same time and new numbers are generated every 6 seconds. To use two-factor authentication, you must enable it from your account. And hopefully today, most popular service providers provide this feature. Moreover, many other electronic gadgets are used to complete the malti-factor authentication. Security keys work as well.

Last word

There is no system or system that can not be hacked during this extreme era of technology. But I still do not see any reason for not using two-factor authentication. It really gives your account a new level of protection. Perhaps the more advanced method will be to complete the malti-factor authentication, but nowhere will it be available to enable it, and it will be wise to make it easy enough.
