What is a realistic trade-off of using multi-factor authentication (MFA) in MIPC?

• A. Always cheaper
• B. Provides no security benefits
• C. Increases security but may impact usability or require additional factors
• D. Replaces the need for TLS

Answer: (C)

Multi-factor authentication strengthens login security by requiring an additional factor beyond a password, such as a one-time code from a device or a biometric check. This extra layer makes it much harder for attackers to gain access even if a password is compromised, which is the core benefit. At the same time, it introduces trade-offs: users may experience extra steps during login, and organizations must manage the distribution and recovery of devices or tokens, plus potential ongoing costs. It’s important to note that MFA does not replace TLS; TLS protects data in transit, while MFA protects the authentication process. So the realistic trade-off is higher security with some usability friction and additional factors or maintenance to support it.
