Two-Factor Authentication (2FA)

Two-Factor Authentication (2FA) is a security protocol that enhances the protection of accounts and sensitive systems by requiring two distinct forms of identification before granting access. This method is an essential layer of security that helps mitigate the risk of unauthorized access due to compromised credentials.

The two factors required in 2FA are typically:

Alternatively, the second factor might be:

The primary advantage of 2FA is that it provides a higher level of security compared to traditional single-factor authentication methods, which typically rely only on a password or PIN. Even if a hacker manages to obtain the user's password, it is unlikely they will also have access to the second authentication factor, making unauthorized access much more difficult.

2FA is widely used across various online platforms, including banking, email providers, social media, and more, to protect users' personal and financial information. As cyber threats continue to evolve, the adoption of 2FA is increasingly becoming a standard security practice for enhancing account security and protecting sensitive data against potential breaches.
