To implement OAuth 2.0 Authorization Code flow with PKCE for a web application, generate a code verifier and challenge, redirect users to the authorization server, and exchange the resulting code for tokens. This Skill guides you through securely setting up this flow.

The best way to manage access and refresh tokens in a Single Page Application is by using a Backend-for-Frontend (BFF) pattern. This approach securely handles token lifecycle management and prevents exposing tokens directly to client-side JavaScript.

Yes, OpenID Connect supports multi-tenant identity federation and step-up authentication. You can configure these identity solutions to manage complex user directories and require additional authentication factors when accessing sensitive operations.

To securely validate access tokens for machine-to-machine services, verify the token signature, issuer, audience, and expiration claims. This Skill provides expert knowledge on best practices for robust token validation across various service architectures.

Use a Backend-for-Frontend pattern for OAuth token storage in SPAs to mitigate cross-site scripting risks. By keeping tokens securely stored in an intermediary backend, you prevent malicious scripts from accessing your authorization credentials.

Yes, you can use OAuth 2.0 for both mobile apps and web applications. This Skill addresses implementation scenarios across various platforms, focusing on best practices for adapting authorization flows and secure token storage to each environment.
