CompTIA Security+ (SY0-501) — Question 361

A company wants to implement an access management solution that allows employees to use the same usernames and passwords for multiple applications without having to keep multiple credentials synchronized.
Which of the following solutions would BEST meet these requirements?

Answer options

• A. Multifactor authentication
• B. SSO
• C. Biometrics
• D. PKI
• E. Federation

Correct answer: B

Explanation

The correct answer is B, SSO (Single Sign-On), as it allows users to log in once and gain access to multiple applications without re-entering credentials. The other options, such as Multifactor authentication (A), focus on enhancing security rather than simplifying credential management, while Biometrics (C), PKI (D), and Federation (E) serve different purposes in identity management and security.
