Summary
This article compares JWT (JSON Web Tokens) and opaque tokens for API security, clarifying the common confusion between bearer tokens and JWT. It covers the differences in validation methods (stateless JWT verification vs. opaque token introspection), performance characteristics, security considerations, and provides guidance on when to use each approach based on specific use cases and requirements.
Key quotes
· 3 pulledWhen discussing modern API security, developers frequently conflate terms like bearer token and JSON Web Token (JWT).
This semantic confusion around access tokens often masks a critical architectural distinction.
A bearer token specifies the transmission mechanism, while the token type determines validation strategy.
Compare JWT vs opaque tokens for API security. Learn the differences in validation, performance, and when to use each approach.
