Editing OAuth 2.0 (section)

== Evaluating (Judgment / Evaluation) ⚖️ ==
=== Evaluation frameworks & tools ===
* Assess token security (entropy, expiry, signature validation).
* Evaluate implementation via OAuth 2.0 Security Best Current Practice (BCP).
* Use test suites such as OpenID Foundation's conformance tests.

=== Maturity & adoption models ===
* Widely adopted across SaaS, consumer apps, and enterprise APIs.
* Active ecosystem with libraries for major languages and platforms.
* Barriers include complexity of correct implementation and security hardening.

=== Key benefits & limitations ===
* Benefits: delegated access, strong security properties, ecosystem support.
* Limitations: complexity, risk of insecure deployments, need for additional identity layer.

=== Strategic decision criteria ===
* Use when third-party or cross-service access delegation is required.
* Avoid for simple internal APIs where mutual TLS or API keys suffice.
* Consider long-term maintainability and compliance requirements.

=== Holistic impact analysis ===
* Enables interoperable, user-centric authorization across the web.
* Strong influence on microservices, identity, and API-driven architectures.
* Ongoing evolution includes OAuth 2.1 consolidation and hardened best practices.
