CompTIA A+ Core 2 (220-1202) — Question 138

Which of the following authentication methods is the best way to prevent users from frequently entering their credentials?

Answer options

• A. Access control list
• B. Single sign-on
• C. Multifactor authentication
• D. One-time password

Correct answer: B

Explanation

Single sign-on (SSO) allows users to log in once and gain access to multiple applications, significantly reducing the need for repeated credential entry. In contrast, an access control list manages permissions but does not address credential input frequency, while multifactor authentication enhances security but does not eliminate the need for users to enter credentials. One-time passwords also require users to input credentials frequently, defeating the purpose of reducing input frequency.
