JWT: trust extends beyond signatures
Each consumer must know which tokens it may accept.

Reading context
A short architecture article. The technical reference supports the topic; hypothetical scenarios and assessment proposals are editorial analysis, not accounts of personal implementations.
Original source ↗The architecture decision
A signed token is not automatically appropriate for every API. Review the expected issuer, intended use and context in which the service accepts its claims.
Practical application
Editorial proposal: document an acceptance contract per consumer. In a hypothetical two-API ecosystem, distinguish audiences and permissions. Avoid turning sample validation into universal configuration.
How to verify
Test tokens intended for another service, expired tokens and inappropriate issuing contexts. Record rejection before business operations. Include key rollover in operational exercises: outages and configuration changes also need predictable behavior.
