Does this skill support the latest OAuth standards?

Yes, it enforces OAuth 2.1 mandatory requirements for 2025, including PKCE for all flows and the removal of insecure implicit grants.

Which programming languages are compatible with this skill?

The skill provides specific implementation patterns and library recommendations for TypeScript, Python, Rust, and Go.

How does it handle complex user permissions?

It provides selection guides and implementation logic for various models, ranging from simple Casbin-based RBAC to complex relationship-based models (ReBAC) using SpiceDB.

What password hashing algorithm is recommended?

The skill mandates Argon2id with OWASP 2025 parameters: 64 MB memory cost, 3 iterations, and 4 threads to ensure resistance against GPU cracking.

Can I implement passwordless login with this tool?

Absolutely. It includes comprehensive guidance for Passkeys (WebAuthn) and cross-device sync strategies for Apple, Google, and third-party managers.

安全与测试

Implements modern authentication, fine-grained authorization, and robust API security patterns following 2025 industry standards.

关于

The Securing Authentication skill provides a comprehensive framework for building production-grade identity and access management systems within Claude Code. It equips developers with the logic and implementation patterns needed to deploy OAuth 2.1, OpenID Connect (OIDC), and passwordless Passkey/WebAuthn systems across TypeScript, Python, Rust, and Go. Whether you are building a simple RBAC system or a complex Relationship-Based Access Control (ReBAC) model using SpiceDB, this skill ensures your architecture follows the latest 2025 security mandates, including mandatory PKCE, Argon2id password hashing, and secure JWT rotation strategies.
