Why Use 2FA (two-factor authentication)?

April 28, 2023

Our company believes that all users should know how to secure data. As data breaches and cyber-attacks increase, it has become increasingly important to implement advanced security measures. The use of two-factor authentication (2FA) can enhance security significantly.

Two-factor authentication (2FA) is a security process that requires users to provide two different forms of authentication to access their accounts. Typically, this involves a combination of something the user knows (like a password) and something the user has (like a smartphone or hardware token). This additional layer of security makes it more difficult for hackers to gain unauthorized access to sensitive data.

So, why use two-factor authentication?

Enhanced Security

The primary benefit of 2FA is that it adds an extra layer of security. Even if a hacker is able to obtain a user's password, they would still need the additional factor to access the account. This makes it much more difficult for hackers to gain unauthorized access.

Protection Against Phishing

Phishing attacks are one of the most common ways hackers try to gain access to user accounts. With 2FA, even if a user falls for a phishing scam and provides their password to a hacker, the hacker would still need the second factor to access the account.


Many industries and regulations require 2FA to be implemented to ensure compliance with data protection and privacy laws. For example, the Payment Card Industry Data Security Standard (PCI DSS) requires 2FA for certain types of transactions.


While 2FA may seem like an extra step, it can actually be more convenient in the long run. With 2FA, users can have peace of mind knowing their accounts are more secure, and they may not need to change their passwords as frequently. Additionally, many 2FA methods (like using a smartphone app) are quick and easy to use.


2FA is a cost-effective security measure that can significantly reduce the risk of data breaches and cyber-attacks. The cost of implementing 2FA is often lower than the potential cost of a data breach or cyber attack.

Tools for 2FA

  • Authenticator apps: These are smartphone apps that generate time-based one-time passwords (TOTP) or use push notifications to authenticate a user's identity. For example, you can use Google Authenticator, Authy, LastPass Authenticator and etc.
  • Hardware tokens: These are physical devices that generate TOTP codes and can be carried on a keychain or in a wallet.
  • SMS or phone call verification: This involves receiving a text message or phone call with a verification code that the user must enter to complete the authentication process.
  • Smart cards: These are small cards with embedded chips that require a PIN to generate a TOTP code.
  • Biometric authentication: This involves using a person's unique physical characteristics, such as fingerprint, facial recognition, or iris scan, to authenticate their identity.

In conclusion, 2FA is a powerful security measure that can significantly enhance security and protect sensitive information. With the increasing number of cyber threats, implementing 2FA is more important than ever. Whether you're an individual or a business, 2FA is a cost-effective way to ensure your accounts are secure.
