CompTIA ITF+ (FC0-U61) — Question 188

A user has been instructed to use unique passwords for accessing each system. Which of the following BEST describes the potential risk of using the same password?

Answer options

• A. The password might be easier for an attacker to guess.
• B. Password compromise would allow access to all of the systems.
• C. Single sign-on would be unable to function correctly.
• D. Systems might reject the password based on different requirements.

Correct answer: B

Explanation

The correct answer is B because if one password is compromised, it can provide unauthorized access to all systems using that password, posing a significant security risk. The other options do not accurately capture the overarching threat posed by password reuse; while they may present concerns, they do not reflect the critical issue of widespread access enabled by a single compromised password.
