Previous Question Next Question

Two-factor authentication (2FA) enhances the security of user accounts by requiring two separate forms of verification before granting access, thereby reducing the risk of unauthorized access. This method aligns with the NIST SP 800-63B guidelines, which recommend multi-factor authentication to strengthen identity assurance.

Example Concept: Two-factor authentication combines something the user knows (like a password) with something the user has (such as a smartphone app or hardware token) or something the user is (biometric verification). This dual-layered approach makes it significantly harder for attackers to gain access, even if they have obtained the user's password, thus providing an additional security barrier against account compromise.

Additional Comment:

2FA can be implemented using SMS codes, authenticator apps, or biometric devices.
It is particularly effective against phishing attacks, as attackers would need the second factor to succeed.
Organizations should encourage users to enable 2FA wherever possible to enhance overall security posture.
Regularly review and update 2FA methods to ensure they remain effective against evolving threats.
