SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires auth0, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill adds DPoP (Demonstrating Proof-of-Possession) token binding to protect API calls, preventing token theft and replay attacks.

Core Features & Use Cases

  • DPoP Token Binding: Cryptographically binds access tokens to a client-held key pair, ensuring tokens cannot be replayed if stolen.
  • Use Case: Ideal for high-value API calls, meeting security or compliance requirements, and for SPAs with elevated security needs.
  • When NOT to Use: Not suitable for server-side environments, APIs that don't support DPoP, or flows requiring token sharing.

Quick Start

Enable DPoP on your API and configure your application to use DPoP tokens.

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

FAQPage Schema
How does DPoP token binding prevent access token theft and replay attacks?

DPoP token binding prevents replay attacks by cryptographically binding access tokens to a client-held key pair. Stolen tokens cannot be reused without possessing the private key, securing high-value API calls against interception.

How do I secure API calls in an SPA with elevated security needs?

To secure API calls in an SPA, enable DPoP on your API resource server and configure the application to use cryptographically bound access tokens. This requires a DPoP-capable authorization server.

Does Auth0 support DPoP token binding for high-value API calls?

Yes, Auth0 supports DPoP token binding for high-value API calls. You must configure a DPoP-capable authorization server and set up the API resource server to validate the DPoP proof.

When should I not use DPoP token binding for API security?

Do not use DPoP token binding in server-side environments, with APIs that lack DPoP support, or in application flows requiring token sharing. It is designed specifically for client-side SPAs.

What is the best way to prevent token replay attacks in SPAs?

The best way to prevent token replay attacks in SPAs is implementing DPoP token binding. It cryptographically binds access tokens to a client-held key pair, ensuring stolen tokens cannot be replayed.
