Implementing OAuth 2.0 with PKCE for a single page application involves using the Authorization Code flow with a code verifier and challenge to secure token exchange. This skill provides blueprints for end-to-end PKCE integration across client-side contexts.

Validating an OIDC ID token requires verifying JWT signatures, audiences, and issuers using discovery documents. This skill provides comprehensive token management guidance, including validation, storage strategies, and secure refresh handling.

Yes, setting up enterprise SSO and social logins is covered with specific integration patterns for identity providers like Auth0, Okta, and Keycloak. It includes configuring discovery documents and managing secure logout flows.

OpenID Connect differs from OAuth 2.0 by adding an identity layer through ID tokens for authentication, while OAuth 2.0 handles API authorization. This skill implements both protocols to support seamless single sign-on and secure API access.

You need to use the Client Credentials flow in OAuth 2.0 for server-to-server API authorization without user involvement. This skill provides production-ready implementation patterns for Client Credentials alongside Authorization Code flows.

Recommended token storage strategies for mobile applications involve secure local storage combined with PKCE to mitigate token interception. This skill outlines secure token management, refresh handling, and logout practices.
