Two Factor Authentication – “Enable It, Secure Accounts”

The online accounts of the authentic end users worldwide are increasingly getting vulnerable to hacking and other malicious attacks. It is because the hackers use the advanced cryptographic techniques/methods to steal your secret password and gain access to your online account. Password, being a single layer of protection, is no longer strong enough in today’s scenario to secure your valuable online accounts and sensitive data from getting compromised. Therefore, it has become must for all the end users to use an additional protection layer along with the secret password in the login process. The benefit of adding extra layer is that if the secret password gets compromised, then the second layer will protect online accounts of the end users from all sorts of security breaches. Two Factor Authentication is an ideal option that secures accounts.

Definition

Two Factor Authentication (2FA), also known as Two Step Verification, is an authentication mechanism that adds an extra security layer in the normal login procedure to verify identity of the user who is logging in to the account. 2FA security method requires two different factors; secret password and a unique verification code or OTP (One Time Passcode), to verify whether the user is authentic or not. The unique verification code is sent to the registered mobile device of the user immediately after entering the correct username and password combination, and is valid only for a few seconds.

Two Factor Authentication security method verifies your identity by requiring both ‘something you know’ and ‘something you have’ when you log in to your account. The thing you need to know is username and a password or a PIN, and the thing you need to have is a mobile phone or any other device that can receive OTP generated by 2FA app.

Different authentication factors for verifying the end users’ identity

Below are the different types of authentication factors:

The knowledge factors (something you know) – username, password, a secret PIN.

The possession factors (something you have) – credit & debit card, mobile phone or any other device.

The inherence factors (something you are) – biometrics like iris, retina, face scan, fingerprint, voice recognition.

Time and Location factors – geographic location.

2FA security method combines any two of the above-listed authentication factors, especially ‘something you know’ and ‘something you have’.

One of the most common examples of Two Factor Authentication security method is cash withdrawal through an ATM using your credit/debit card. For withdrawing cash successfully, you enter card; something you have, and a secret 4-digit PIN; something you know. Without the availability of both card and PIN, cash withdrawal is impossible even if you are a real owner of the card. With 2FA, if someone else hacks your secret password, then he needs access to your registered mobile device as well for receiving unique verification code and logging in to the account. In this way, Two Factor Authentication secures your precious digital assets from all sorts of security breaches.

Conclusion

2FA greatly increases your valuable online accounts, sensitive data and information security, and is the single most effective security measure after using highly complex passwords. That’s why it can be concluded that all the authentic end users worldwide must enable Two Factor Authentication security method for a better account security.

Block Unauthorized Access with Two Step Verification

The online accounts, data and information protection has always been a major concern for all the authentic end users worldwide. With malicious attacks or security threats increasing at an alarming rate these days, compromises in the internet security have become more threatening than ever. Being an end user, you need to do everything i.e. put every possible step to ensure that your online accounts and sensitive data are protected from all sorts of cyberattacks. The hackers are using the latest technologies to find your valuable online accounts login credentials. So, you need to be one step ahead of them (hackers) to make their task tougher, or impossible, to accomplish successfully.

One powerful method that provides a strong defence against all types of security breaches on your online accounts, or blocks unauthorized access, is Two Step Verification security method.

What is Two Step Verification?

Two Step Verification (TSV), as the name suggests, introduces a second step to your login. It provides an extra layer of security to the sign in process for verifying identity of the user. TSV security method requires you to enter a time sensitive unique verification code after you enter your username and password combination. The unique verification code or OTP (One Time Passcode) is sent to the registered mobile device of the user, and is valid only for a few seconds. This security method is also referred to as Two Factor Authentication, or simply 2FA.

Once Two Step Verification method is enabled on your online account, you are required to enter an additional piece of information to prove your identity, after entering the secret password. This will prevent unauthorized users from accessing your account even if they have obtained your login credentials.

Possible authentication factors used in Two Step Verification

The knowledge factors (something you know) – username, password, PIN.

The possession factors (something you have) – credit & debit card, mobile phone.

The inherence factors (something you are) – biometrics like iris, retina, face scan, fingerprint, voice recognition.

Why use Two Step Verification?

The main reason of using Two Step Verification is that the state of the online accounts and data security is changing continuously. Hackers are getting more and more advanced when trying to hack your secret login credentials, and the old security methods won’t work any longer. Today, strong passwords and security questions simply aren’t the ultimate security solutions they used to be earlier. Two Step Verification has been successful in securing compromised accounts even when the secret password has been stolen. By requiring an additional source of verification before logging into your online account, this security method makes it harder for those users who have access to your password to get inside your account and do any real damage.

Conclusion

Two Step Verification is a more secure solution than just passwords. It works by requiring two different methods to authenticate yourself. Cash withdrawal through an ATM is the example of Two Step Verification. For withdrawing cash, you need your card (something you have) and a secret 4-digit PIN (something you know). If you lose your card, your money is still safe. Anyone who finds your card will not be able to withdraw your money, as they do not know your PIN. The same is true if they only have your PIN and do not have the card. An attacker must have both to compromise your ATM account. This is what makes Two Step Verification method so much secure; you have two layers of security.
