Security experts recommend using two-factor authentication to deter hackers. If you use two-factor authentication, you can combine a password with an authentication code sent via text message or generate by an app like Google Authenticator. Over 555 million passwords were exposed in data breaches affecting banks, social networks, and other online services. Two-factor authentication could stem this tide.
What Is Two Factor Authentication?
The method is called two-factor authentication (2FA). It involves two additional security levels. Both of them must be present for the system to function. Also known as double factor authentication, two-factor authentication (2FA) requires clients to provide two different components of verification in order to verify themselves. Using two-factor authentication makes it easier to protect both the client’s credentials and assets they can access.
The client provides just one factor for single-factor authentication, usually a secret key or password. One of the factors in two-factor authentication is a secret key. Second, a unique factor, generally a security token or a biometric factor.
Is 2FA Not Stopping Hackers?
Two-factor validation, while enhancing security, is only as secure as its weakest link. For instance, equipment tokens are only as secure as the person or company that guarantees them.
In 2011, RSA Security disclosed that its SecurID verification tokens had been hacked, one of the most high-profile incidents of a compromised two-factor framework. Using a record recovery measure to defeat two-factor authentication can also sabotage the method. It resets a user’s present password and sends them a temporary one to permit the user to log into their accounts. The business Gmail records of the CEO of Cloudflare were compromised in this way.
In spite of the low cost, ease of implementation, and user-friendliness of SMS-based 2FA, it is subject to numerous attacks. In its Special Publication 800-63-3: Digital Identity Guidelines, the National Institute of Standards and Technology (NIST) discourages SMS for two-factor authentication. NIST states that OTPs transmitted by SMS are too vulnerable to attacks on mobile phone networks and malware that can intercept or redirect text messages due to mobile number portability attacks and attacks against the mobile phone network.
How multi-factor authentication can help you
A real-life example is the easiest way to understand multi-factor authentication. Is your home equipped with a safe containing many valuable possessions? A code protects the safe, providing one level of security. What if someone manages to crack the code? The safe can be opened. Consider the possibility that you could also need a device that would scan your face or a text message to open a safe in addition to a code. It makes it more difficult to open the safe if someone else does not have those steps.
Similarly, multi-factor authentication makes it more difficult to access your account. Imagine that you have enabled multi-factor authentication for your social media account. Your account cannot be accessed even if someone guesses your password. Logging in also requires another piece of information.
Elements of two-factor authentication
A two-factor authentication is a form of multi-factor authentication, and it is used whenever two authentication factors are needed to access a system or service. Even when two factors in the same category are used, it still doesn’t count as 2FA. For example, SFA is still considered when a password and shared secret are required since both belong to the knowledge authentication factor category.
Future of authentication
The use of three-factor authentication is normally relevant to environments that require greater security, which usually involves a physical token and a password in conjunction with biometric information such as fingerprints or voiceprints. When it comes to authentication, relying solely on passwords is no longer a practical choice, either due to security concerns or user experience. Despite the fact that legacy security tools, such as password managers and multi-factor authentication, promise to fix the login and password problems, they still use an essentially outdated architecture: password databases.
Conclusion:
A future for authentication lies in utilizing more approaches to convince machines we are who and what we claim to be. As a result, we will also become less vulnerable to security breaches. Until then, you should use a combination of verification factors whenever possible.
