hard🧠 Conceptual Q10 of Q15

Rest API - Authentication and Authorization

ABecause it skips the authorization server

BBecause it uses GET requests instead of POST

CBecause the access token is never exposed to the user-agent

DBecause it does not require user authentication

Step-by-Step Solution

Solution:

Step 1: Understand token exposure differences
Authorization Code Flow exchanges code server-side, so access tokens are not exposed in URLs or browser.
Step 2: Contrast with Implicit Flow
Implicit Flow returns tokens directly in URL fragments, exposing them to the user-agent and potential attackers.
Final Answer:
Because the access token is never exposed to the user-agent -> Option C
Quick Check:
Authorization Code Flow hides tokens from browser [OK]

Quick Trick: Code flow keeps tokens off browser, safer than implicit [OK]
