CompTIA Security+ (SY0-601) — Question 792

An internet company has created a new collaboration application. To expand the user base, the company wants to implement an option that allows users to log in to the application with the credentials of other popular websites. Which of the following should the company implement?

Answer options

• A. SSO
• B. CHAP
• C. 802.1x
• D. OpenID

Correct answer: D

Explanation

The correct answer is D, OpenID, as it allows users to log in to various applications using one set of credentials from a trusted provider. Option A, SSO, is broader and refers to single sign-on systems in general, while CHAP (B) is a protocol for authenticating users on networks. 802.1x (C) is a network access control standard and not directly related to logging in with credentials from other websites.
