CompTIA Security+ (SY0-501) — Question 611

A company is implementing MFA for all applications that store sensitive data. The IT manager wants MFA to be non-disruptive and user friendly. Which of the following technologies should the IT manager use when implementing MFA?

Answer options

• A. Onetime passwords
• B. Email tokens
• C. Push notifications
• D. Hardware authentication

Correct answer: C

Explanation

Push notifications are the most user-friendly and non-disruptive form of MFA, as they allow users to approve login attempts with a simple tap on their mobile devices. Onetime passwords and email tokens can be cumbersome since they require users to enter codes, and hardware authentication often involves additional physical devices that can complicate the user experience.
