Frequently Asked Questions about oauth-expert

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement OAuth 2.0 Authorization Code flow with PKCE for a single page application?▼

OAuth 2.0 Authorization Code with PKCE secures single page applications by generating a cryptographic code verifier and challenge to prevent authorization code interception during the token exchange process.

What is the best way to handle JWT validation and token lifecycle management across web and mobile platforms?▼

JWT validation and token lifecycle management require verifying signatures and claims, alongside implementing secure token storage and refresh strategies optimized for distinct web and mobile platform constraints.

Does this guidance cover step-up authentication and multi-tenant identity federation patterns?▼

Yes, this guidance covers step-up authentication and multi-tenant identity federation patterns, providing specific architectural strategies for managing varying access levels and federated identity across isolated tenants.

When do I need OpenID Connect instead of standard OAuth 2.0 for user authentication?▼

You need OpenID Connect instead of standard OAuth 2.0 when your application requires explicit user authentication and identity details via an ID token, rather than just delegated API access via standard OAuth 2.0.

How do I design scopes and use token exchange patterns for machine-to-machine (M2M) authorization?▼

Design scopes and use token exchange patterns for M2M authorization by defining granular access boundaries and exchanging tokens to securely delegate API access between services without user interaction.
