What is 2FA?

Two-Factor Authentication (2FA) is an enhanced security process that requires users to provide two different authentication factors to verify their identity. This additional layer of security ensures that even if one factor, such as a password, is compromised, unauthorized access is prevented without the second factor. Typically, the two factors include something you know (a password) and something you have (a mobile device or hardware token).

2FA vs. Single-Factor Authentication

Single-factor authentication relies solely on a password to grant access to an account. While convenient, this method is vulnerable to various attacks, such as phishing, credential stuffing, and brute force attacks. In contrast, 2FA provides a more robust defense by requiring an additional verification step, significantly reducing the risk of unauthorized access.

The History of 2FA

The concept of multi-factor authentication has been around for decades, with early implementations in the form of security tokens and smart cards. However, it wasn't until the rise of online services and increasing cybersecurity threats that 2FA became a mainstream security measure. Today, 2FA is widely adopted across various industries, from banking to social media, as a standard practice for protecting sensitive information.
