FAQPage Schema
How do I implement Azure AD authentication in a React SPA?▼

Implementing Azure AD authentication in a React SPA involves using MSAL.js to establish single sign-on and secure API access. This setup utilizes the Authorization Code Flow with PKCE to prevent common configuration errors.

How do I validate Azure AD JWT tokens in Cloudflare Workers?▼

Validating Azure AD JWT tokens in Cloudflare Workers involves using the jose library to verify token signatures and claims. This secures your serverless backend by ensuring only authenticated users access data.

Why am I getting AADSTS errors when configuring MSAL React?▼

AADSTS errors during MSAL React configuration usually stem from incorrect application registration or redirect URI mismatches in Microsoft Entra ID. Correcting these MSAL configuration pitfalls prevents authorization failures.

Can I use MSAL.js with Cloudflare Workers for full-stack authentication?▼

Yes, you can use MSAL.js with Cloudflare Workers for full-stack authentication by implementing the Authorization Code Flow with PKCE on the frontend and validating issued JWTs on the backend. This secures both client and API.
