CompTIA ITF+ Practice Test 2025 – 400 Free Practice Questions to Pass the Exam

Two-factor authentication (2FA) is a security process that enhances the protection of accounts and sensitive information by requiring two different forms of identification from users before granting access. This typically involves a combination of something the user knows (such as a password) and something the user has (like a smartphone that can generate a verification code or a hardware security token).

The use of two distinct forms of authentication greatly reduces the risk of unauthorized access, as even if one credential (such as a password) is compromised, an attacker would still need the second form of identification to gain access. This layered approach to security is effective in mitigating the risks of hacking, phishing, and other forms of security breaches, making it a crucial component of modern digital security practices.

In contrast, other choices provided do not accurately describe two-factor authentication. For instance, securing a Wi-Fi network with multiple passwords pertains to network security rather than user authentication. Similarly, using two backups relates to data redundancy and recovery, while enhancing graphics quality pertains to system performance and visual fidelity, neither of which involves authentication processes.
