When it comes to ensuring cybersecurity, Two-Factor Authentication (2FA) is one of the the most popular authentication methods. Individuals usually rely on basic password security, but cybercriminals are sophisticated enough to breach passwords and harvest sensitive data. Here, 2FA adds an extra layer of security by requiring two methods of authentication to access any databases or sites.
Let’s have a look at exactly what 2FA is and how it protects the data.
What Is Two-Factor Authentication?
Two-Factor Authentication is an electronic method used to authenticate user access on databases, websites, or applications. If an individual wants to access the data, they need to show two pieces of evidence, including the password. It restricts unauthorized access to databases even in case a cybercriminal breaches password security. From PINs to USB drives, 2FA offers the utmost security to all databases while still being convenient to users.
What Are Some Two-Factor Authentication Options?
-
OTP
OTP (One Time Password) is the easiest and the securest 2FA method. It is a temporary code that a user requires to fill while accessing the data or making payments. Once a user enters the password, they get a code or OTP via the registered mobile number and Email address.
-
Security Questions
Besides OTP, security questions are also an optimal way to ensure internet security. Whenever an individual attempts to log in, they may be the security question for the access. Users can select questions that only they know the answer to, which provides a high level of security.
-
Biometrics
Everyone has unique biometrics and can optimize password security with convenience. An individual can use their fingerprints, eyes, and palms to authenticate themselves during login.
How Does 2-Factor Authentication Work?
Let’s take a real-life example to understand how Two-Factor Authentication works. Suppose an individual wants to access their net banking account. The user may be required to fill out the correct password and OTP while making a financial transaction. Even if an unauthorized user gets the password, this person cannot conduct financial transactions without the OTP. In simple words, OTP adds an authentication layer to password security while accessing the data.
Two-Factor Authentication vs. Multi-Factor Authentication
Multi-Factor Authentication (MFA) is similar but more vast concept compared to 2FA. In MFA, a user can add more than two security options to protect data from unauthorized users. Unlike 2FA, Multiple Factor Authentication allows individuals to combine multiple forms of security during the registration. This electronic method is securer and more reliable when compared to Two-Factor Authentication. That’s the reason why US Government agencies use Multi-Factor Authentication Solutions for PIV (Personal Identity Verification).
Conclusion
Two-Factor Authentication is improving data encryption and security. It integrates with password security and ensures that data stays safe from cybercriminals. It’s also a great way to keep databases safe without compromising convenience.
