What problem does it solve?

Implementing OAuth 2.1 securely is complex and error-prone, leading to token leakage, insecure redirects, and weak client/server protections. This Skill consolidates the security requirements to guide TLS, redirect handling, and token-binding practices for modern OAuth deployments.

Core Features & Use Cases

  • TLS enforcement across all endpoints (with loopback exceptions for native apps) and TLS version guidance.
  • PKCE is mandatory for public clients and strongly recommended for confidential clients.
  • Removal of Implicit and Resource Owner Password Credentials grants; encourage Authorization Code with PKCE.
  • Secure redirect handling using exact redirect_uri matching and recommended status codes (e.g., 303 See Other).
  • Token binding options including DPoP and Mutual TLS to prevent token replay.

Quick Start

Apply OAuth 2.1 security guidelines by enforcing TLS on all endpoints, enabling PKCE for public clients, and adhering to safe redirect practices.
