CompTIA A+ Core 1 (220-1101) — Question 530

Following a security breach that revealed employee username and password information, an organization would like to implement additional security for users logging in to company devices. Which of the following would be the best solution for the organization to use?

Answer options

• A. Biometric authentication
• B. Peer-reviewed log-ins
• C. Log-in scripts
• D. One-time tokens

Correct answer: D

Explanation

One-time tokens are a strong method of authentication because they provide a unique code for each login attempt, making it difficult for unauthorized users to gain access. Biometric authentication, while secure, may not be feasible for all users or devices. Peer-reviewed log-ins and log-in scripts do not significantly enhance security in the same way as one-time tokens.
