OpenID Connect

Secure API Design and Governance APIs are the backbone of modern software, linking apps, services, and devices. Secure API design and governance means building defenses into the surface you expose and maintaining clear rules for teams that use it. The goal is to protect data, reduce risk, and keep development steady. Start with security by default. Require authentication on all endpoints, and apply least privilege. Use standards like OAuth 2.0 and OpenID Connect for user and app tokens. Consider mutual TLS for service-to-service calls. Validate inputs and outputs with strong schemas, and enforce strict content-type checks to reduce attack surfaces. Keep tokens short-lived and rotate keys regularly. Document expectations in an OpenAPI specification so developers and machines share the same contract. Add rate limits, and provide safe error messages that avoid leaking internal details. ...

Building Secure Web Apps: OAuth, JWT, and Beyond Secure web apps hinge on clear identity and careful token use. OAuth 2.0 lets apps access user data without passwords, while OpenID Connect adds login. JWTs carry information in a compact token, but they must be validated and kept short-lived. In practice, combine OAuth with OpenID Connect for sign-in and use PKCE for public clients like mobile apps or browser SPAs. Treat access tokens as keys to APIs. Protect them in transit with TLS and store them securely; httpOnly cookies are a safe default for web apps. Request only the permissions you need with scopes. ...
