Step-by-Step Solution
Solution:
Step 1: Understand token refresh
Refreshing tokens centrally avoids token mismatch.Step 2: Avoid token generation in services
Generating tokens in each service breaks trust chain.Step 3: Avoid downstream direct refresh
Downstream requesting tokens complicates flow and security.Step 4: Avoid embedding refresh tokens everywhere
This increases attack surface and complexity.Final Answer:
Use a centralized authentication gateway that issues tokens and refreshes them, forwarding the valid token downstream -> Option BQuick Check:
Central gateway manages tokens and refresh securely. [OK]
Quick Trick: Centralize token refresh to maintain JWT consistency [OK]
Common Mistakes:
MISTAKES- Allowing each service to generate tokens independently
- Letting downstream services refresh tokens directly
- Passing refresh tokens in every service call
