What does two-factor authentication (2FA) help mitigate?

• A. The risk of malware infection
• B. The risk of unauthorized access
• C. The risk of account suspension
• D. The risk of identity theft

Answer: (B)

Two-factor authentication (2FA) significantly helps mitigate the risk of unauthorized access to accounts and sensitive information. Essentially, 2FA adds an additional layer of security beyond just a username and password. Even if a user's password is compromised, an attacker would still need access to the second factor, which typically involves something the user possesses (like a smartphone app or a hardware token) or something inherent to the user (like a fingerprint or facial recognition). This two-step verification process makes it much more difficult for unauthorized individuals to gain access to accounts, thus greatly reducing the likelihood of account breaches. By requiring both knowledge (the password) and possession (the second factor), 2FA effectively enhances the overall security posture against unauthorized access attempts. Other options like the risk of malware infection, account suspension, or identity theft do not directly relate to what 2FA addresses. While 2FA can indirectly contribute to reducing some complexities surrounding identity theft by protecting accounts, its primary function is specifically aimed at preventing unauthorized access.
