CompTIA Security+ (SY0-501) — Question 370

Which of the following uses tokens between the identity provider and the service provider to authenticate and authorize users to resources?

Answer options

• A. RADIUS
• B. SSH
• C. OAuth
• D. MSCHAP

Correct answer: C

Explanation

OAuth is a protocol that enables token-based authentication and authorization between different entities, making it the correct choice. RADIUS is a network protocol for remote user authentication, SSH is used for secure shell access, and MSCHAP is an authentication protocol, none of which specifically use tokens in the same way as OAuth.
