OAuth

What This Skill Does

The OAuth skill for OpenClaw provides an integrated, secure framework for implementing OAuth 2.0 and OpenID Connect (OIDC) workflows. It acts as an orchestrator for identity management, handling authorization code flows with PKCE, managing client credentials, and validating security parameters like state and nonce. This skill simplifies the complexities of token lifecycle management, ensuring that tokens—both access and refresh—are handled securely while preventing common vulnerabilities like CSRF, XSS, and authorization code interception.

Installation

To install this skill, run the following command in your terminal within the OpenClaw environment: clawhub install openclaw/skills/skills/ivangdavila/oauth Ensure you have the necessary environment permissions to communicate with your target authorization server before initiating setup.

Use Cases

This skill is designed for developers who need to integrate third-party authentication into their applications or manage service-to-service communication. Common use cases include:

• Enabling "Log in with Google/GitHub/Microsoft" in web or mobile applications.
• Implementing secure backend-to-backend API authentication using the Client Credentials flow.
• Securing CLI tools or Smart TV applications using the Device Authorization Grant.
• Enforcing OIDC compliance by handling ID token verification and user profile claims.

Example Prompts

1. "OpenClaw, guide me through setting up a secure Authorization Code flow with PKCE for my React SPA, including how to generate and verify the code_verifier."
2. "I need to implement a service-to-service integration. How should I configure the OAuth skill for a Client Credentials flow, and what are the best practices for token rotation?"
3. "Please review my current implementation of the OAuth callback handler and help me identify if I am correctly validating the state parameter and preventing CSRF attacks."

Tips & Limitations

• Security Priority: Always prioritize the Authorization Code flow with PKCE. Never use the deprecated Implicit flow.
• Storage: Avoid storing tokens in localStorage; opt for httpOnly cookies or in-memory storage to mitigate XSS risks.
• Validation: Always validate the iss (issuer) and aud (audience) claims on any JWT received to prevent token confusion attacks.
• Scope Management: Request only the absolute minimum scopes required for your application to build user trust.
• Limitations: The skill assumes the underlying authorization server supports standard OAuth 2.0 specs. It does not replace the need for a compliant identity provider (e.g., Okta, Auth0, Keycloak).
