What does two-factor authentication improve?

Two-factor authentication (2FA) significantly enhances account security by requiring users to provide two different forms of identification before gaining access to their accounts. This process typically combines something the user knows (like a password) with something the user has (such as a mobile device or hardware token). By implementing this layered security mechanism, even if a malicious actor obtains the user’s password, they would still be unable to access the account without the second factor, thereby reducing the likelihood of unauthorized access.

In the context of account security, two-factor authentication serves to thwart many common attack vectors, such as phishing, credential theft, and brute-force attacks. This added security layer ensures that even if one aspect of authentication is compromised, the account remains protected by the requirement for the additional factor. As a result, users can have greater confidence that their sensitive information is safeguarded, making it a crucial practice in today’s cybersecurity landscape.
